Personally I think that defensive technology like this is fantastic. It means that innocent citizens will be protected from constant bombardment or thread of bombardment by cheap mass produced rockets or drones. Israeli civilians have faced bombardment by tens of thousands of rockets from Gaza for the last 20 years [1].

Outside the Middle East there's many areas threatened by combatants with similar cheap missiles. Perhaps Ukraine is an obvious one. We're seeing rises in conflicts across parts of Africa, Cambodia/Thailand, Pakistan/India. Many governments are looking into buying these to protect their countries.

This technology hopefully can protect populations from destabilizing forces funded on the cheap by foreign powers. Machine guns changed warfare [2] and drones have been a similar massive change in warfare making it cheaper and easier to attack and destabalize regions. Though of course there's downsides as well [3].

I'll bite. Yes, I believe that even if you as a civilian personally voted for someone who ended up being a horrible genocidal dictator, that doesn't make it ethical for the other side to target bombs at you; warfare should be directed at combatants, or at least at the industrial base rather than indiscriminately at civilians.

Israel invests in defending their civilians with technology like Iron Beam.

In contrast the Gazan government strategically uses humans shields [2, 3] and despite this the majority of Palestinians still support starting this war by attacking civilians on Oct 7th [1]. Defense technology doesn’t help if you don’t want it unfortunately.

Hamas also has hundreds of miles of tunnels which civilians aren’t allowed to use.

To say that israel invests in defense is at least 1/4 untrue, since the US sends billions every year. The US gave them about 7b cash last year, which is around 1/4 of their defense budget, and doesn’t include things like stationing carriers nearby, or doing airstrikes on houthi blockades.

Three thoughts:

1. Just to repeat myself from another comment on this thread, there is no such thing as a defensive weapon. Were it not for the various missile shields, the Israeli state wouldn't act with wanton abandon against its own citizens and its neighbours. All of the various war crimes and terror attacks are a direct consequence of the effectiveness of a "defensive" missile shield.

Let me pose this question to you: if these were purely defensive technologies, why don't we give them to everyone, including the Palestinians? and

2. Israel has already ruled out giving Ukraine the anti-missile (and assumedly anti-drone) defenses [1]; and

3. Many people, yourself included it seems, need to examine these conflicts around the world through the lens of historical materialism.

Take the genocide and conflict in Sudan. The SAF are arguably the ones with the "cheap rockets" here. Should we be giving the RSF anti-drone technology? The RSF are backed by the UAE using US weapons. Why? To loot Sudanese gold.

Why did Russia invade Ukraine? Territory, access to the Black Sea, resources and to create a land bridge to Crimea that had otherwise become extremely expensive to maintain as a colonial outpost. Like, just look at a map of controlled territory.

But why is it in a stalemate? In part because Russia is a nuclear power but also because the West is unwilling to let Ukraine do the one thing it could do to defend itself properly and that is to attack Russian energy infrastructure. Despite the sanctions, Russia is still allowed to sell oil and gas to places like Hungary, Slovakia, France, Belgium, India and China.

Back to the Middle East, we have Yemen, who was devastated by war and genocide at the hands of another US ally, Saudi Arabia.

The solution to these conflicts isn't more weapons, not even "defensive weapons". It's solving the underlying economic conditions that created that conflict in the first place.

I think you have it backwards. Israel tolerated something like ~30k rocket attacks from Gaza (between 2005-2023) before finally launching a major military campaign that sought to remove Hamas from power.

It would normally be absurd to expect a state with military superiority to tolerate ~30k rocket attacks from its weaker neighbor. That was only tenable because Israel's air defenses mitigated the bulk of the damage.

If Israel's air defenses and bunkers suddenly disappeared, Israel would be forced to respond far more aggressively to each terrorist attack.

I'm not sure that's true, before Iron Dome, Israel would respond to many rockets from Gaza by firing mortars back at where the rocket was launched from, often the roof of an apartment building or similar, causing civilian casualties.

After Iron Dome, a lot of rockets were simply intercepted and ignored, because there was no longer political pressure from Israelis seeing rockets land in their villages and wanting to hit back.

Put another way, I don't think we would be against new clothing that made bullets less effective, even if it remains terrible that such clothing is needed.

Especially as AI becomes better and cheaper and suicide drones become more nimble and autonomous. If you have seen any of the horrifying footage out of Ukraine you will understand how badly we need more effective and cheaper drone defense as soon as possible.

Yeah, I see this as ultimately a wash.

In Russia/Ukraine, drones have proven to be a very real threat to deal with (arguably also in Iraq).

What this means is wealthy nations will snatch up or recreate this and deploy it. That will stop smaller resistance forces from either defending or attacking. Depending on the nation in question this could both good or bad. Just like drones, guns, or tanks.

Effectively, this puts the status quo back to where it was before mass drone deployments.

That laser station will not last in Ukraine an hour and will be destroyed either by missiles or drone swarm.

What Ukraine have found a net launcher is effective and cheap solution against drones and may allow more use of tanks and heavy armor vehicles again in 2026. Then shotguns with a special ammunition is effective. Then against fiber drones a fence with moving wire works surprisingly good to cut the fiber.

Israel saw over 16,000 rocket attacks last year from fundamentalist groups like Hamas, Hezbollah, Iran, and Yemen. The Iron Dome intercepted ~90% of them, resulting in thousands of lives saved.

As a real example of this, the only reason a deeper conflict didn't develop with Iran this year was because Iran demonstrated they could overwhelm the various layers of Israel's missile shield and Iran seriously depleted the various munitions used by those air defense systems (eg interceptors, THAAD) and those take a long time to replenish.

If a missile shield is a weapon, because of its affordances, then any object is a weapon. And while that's marginally true I don't think we get anywhere by entertaining category errors.

If something enables aggression, because it makes counter attacks unreasonable, that seems like a fairly nice thing to have more of, in a world where destruction is far too easy and construction is fairly hard.

It'll get a lot of time to react at that energy as it's not going to "instantly" fry anything*. That's probably less energy/m2 than consumer heat guns, especially if consider that these drones are likely going to get sprayed in reflective paint. Easy defense for the drone would be just: get into a spin to get roasted evenly -> shut off -> fall for a few hundred meters, cooling using air that rushes by to counteract the laser further -> catch itself once it lost the laser.

That would force these laser systems to point each drone until it either visibly goes up in flames or impacts the ground (which means you also need to be able to track them all the way down), otherwise you can't be sure it won't just snap back to life once you started engaging the next drone.

I don't feel like 10kw/m2 would be anywhere near useful. It's gotta be more than that.

* Stadium floodlights aren't going to instantly grill any bird that flies in front of them either, and they reach that ballpark.

If these things are even 50% efficient, then power delivery is really not a problem these days. Most EVs have no problem delivering 200kW for quite a few seconds at a time, limited mostly by components getting warm. Higher-end EVs are generally rated for 300-500kW.

It isn't hard to imagine a scenario where person x is killed since they are marked as a 'bag guy' and as part of being marked every person they were next to for the last few days was also marked as likely enough to be bad guys to kill as well. All that has to be done is push a button. It is a scary, and unfortunately all to possible, future if not now.

The presupposition here being that Israel has a right to defense and that the poor people being occupied, living under apartheid, being slaughtered and displaced should possess no such right to resist, has been a hallmark of zionist propaganda for ages now.

This is an astonishing revisionist take on the reality on the ground.

Israel unilaterally disengaged from GAZA in 2005 and pulling out generations of Jewish settlement in the process. By 2006 GAZA has zero Jews, and 2007 Gazans elected HAMAS who fired rockets at Israel because they want to free Palestine from the river to the sea, AKA eliminate Israel. October 7 attack is a culmination of that, and between then and now, HAMAS didn't forget to build their military base in the mix of civilians and using civilian targets as shield. So that they can blame Israel for every single Palestinians death, including the death cause by their own firing.

The situation in west Bank is qualitatively the same.

No, protecting your people from terrorist is not apartheid, and Israel has no interest to build iron beam and/or build wall--which the west misinterprete as apartheid-- if the neighbors had no intention to eliminate them.

The issue with that type of reasoning is that if you swapped the parties the sentences would be the same. "Palestine removed generations of settlements from Israel, but was forced to attack because Israel wanted to wipe them out." You need to think in terms of principles that can apply equally to everybody.

Though your comment is phrased ambiguously ( not sure you are referring to the Arabs in Israel, or Arabs in Gaza/west bank), I try to respond to both.

For Arabs in Israel, it is important to note that inside Israel parliament knesset, there are Arab representatives, some who even call for the soft dissolution of the state itself ( rights of return). They are the descendants of the Arabs who didn't leave Israel during the 1947 Israel independent war. So no, Arabs there are by and large not removed at all by anyone. By contrast, there are zero Jews in Gaza or West Bank. Jews enter those places at their own peril, they could be lynched.

The Arabs in GAZA/West Bank are not under Israeli jurisdiction, and by their actions and words they are still declaring war on Israel, despite that they launched the war first every single time, and lost every single time, and play victim every single time. If Israel wanted to wipe them out then there is no need for Israel to accept the 1947 partition, the David peace accords (2000) or the Oslo accords (2008), which Palestinians all rejected wholesale. If Israel really wanted to wipe them out, the GAZA war following October 7 terrorist attack would be over by the next day as Israel dominated absolutely militarily.

Really, the conflict is really that simple. One side, Israel, wants peace, and the other, the Palestinians, who don't ( as captured by their slogan, "from the river to the sea Palestinians will be free", do look up on where is the river and where is the sea if you have doubt).

It is made complicated only because a lot of people try to obscure the reality. But that's the topic for another day.

Not really relavent. Occupying powers still have the right to self-defense. Certainly they have the right to take defensive measures to prevent attacks on the civilian population of their primary territory, which is what is being discussed here.

> Israel won't let food into Gaza in reasonable quantities

As far as i understand the food situation in Gaza has now stabilized. However even if Israel was illegally restricting food into gaza, that wouldn't have any bearing on the legality of them setting up air defense systems on their own territory.

> All in violation of international law

Being an occupying power is not in and of itself a violation of international law. (The food thing might be. Israel is allowed to put certain restrictions on aid, but groups like the ICC have argued that the restrictions were beyond what was permissible under international law. Personally, even though it is incredibly unlikeky to happen, i hope the issue goes to trial at the ICC so we get a firm answer. However even if true, it does not mean Israel loses every right it has under international law)

I think Israel has a right to defense qua state and Palestinians have a right to resist qua subjects of unjust rule. These aren’t really contradictory positions, and both are pretty standard from a “this is what the UN says” ground truth[1][2].

(This is distinct from a state’s “right to exist,” which is nonsense. But once a state does exist, it has the right to defend itself by definition.)

Yes it can, and it's ludicrous to suggest otherwise. Russia believes it has the natural right to reclaim what it considers to be Russian territory. Ukraine believes it has the right to be free. So everyone should just put down their weapons and come to an agreement based on these rights?

The fallacy at the heart of your argument is that there is somehow some greater single truth, and that each side agrees that it is the greater single truth, and that everyone will just peaceably agree to follow the single greater truth because it is the single greater truth. Nothing could be less human. What are we, the Borg? We're supposed to follow some hive mind?

> something simple, like tying sanctions to murders of civilians

Not even remotely simple. Define sanctions, murders, civilians. The US bombing "drug" boats in the Caribbean, are those civilians? International law recognizes that collateral damage can legitimately happen during legitimate military operations. Is the collateral damage "murder"? How far should sanctions go? Sanction enemy banks (layer 1)? Sanction citizens of neutral countries who do business with the enemy country (layer 2)? Sanction citizens of neutral countries who do business with other citizens who do business with the enemy country (layer 3)?

They don’t both have a right to kill each other! Both “defense” and “resistance” (w/r/t the goal of self determination) have precise bounds; not all forms of warfare or violence are considered justifiable under either. Much of what Israel has done in the current conflict goes well beyond a charitable read of its right to defense, but this doesn’t imply that all defense adaptations are illegitimate.

I think everyone (myself included) has a right to actual self-defense, just not the false version we've been seeing.

Here's my peace plan: Blow up or starve kids on the other side +1 sanctions. Intercept a drone or rocket +0 sanctions. Say you're sorry and reduce arms by 10% -1 sanctions.

If the US alone did this they'd stop with all the murders in days to weeks.

Of course the state of affairs where random online commenters can think of better answers than the individuals in charge is only due to a lack of a desire for peace at high levels! There is nothing complicated about it at all.

Gaza (Hamas), the West Bank (Fatah), and Lebanon (Hezbollah) are the reason this technology is needed in the first place: violent religious fundamentalists firing cheap rockets at Jewish cities because of religious hatred. Over 16,000 rocket attacks on Israel last year alone.

Thanks to the Iron Dome technology, nearly 90% of such attacks were intercepted, saving thousands of lives.

This new Iron Beam technology is more precise and cheaper, and will likely save even more lives.

Israel has never been interested in a peace deal.

Mirrors are not effective enough. Shielding drones from energy weapons seems like a similar problem to entering Earth’s atmosphere, you want to shield it in a way that will blast away safely and ideally diffuse the laser, so the energy is spread over a larger space. I suspect larger lasers will likely aways win, since there is only so much shielding can do. At which point we could end up with transformers like drones that are built to be broken apart mid flight and yet still deliver damage. I feel like defending drones could become possible with energy weapons but only under ideal weather conditions.

On the last day of the year, I am taking a few minutes to linger on this. At face value, most would agree with this, myself included. But I think we can dive one layer deeper. There are different schools of thoughts whether mankind is inherently good or evil. Over the years, I have become pretty firm believer that every person has the innate capacity for both good and evil, and the outcome is determined by both character and circumstances. Solzhenitsyn famously wrote (quote by Gemini):

"The line separating good and evil passes not through states, nor between classes, nor between political parties either—but right through every human heart—and through all human hearts. This line shifts. Inside us, it oscillates with the years. And even within hearts overwhelmed by evil, one small bridgehead of good is retained. And even in the best of all hearts, there remains … an unuprooted small corner of evil."

If you subscribe to this, then a weapons system can also be a force for good, if used by an entity for the purpose of "peace through strength". The strength keeps our innate capability for evil in check, as the consequences for evil would be guaranteed. A case in point is the MAD doctrine for nuclear weapons which has prevented a world war for the last 80 years.

I'd appreciate philosophical replies. Am I wrong, either in a detail or at the core of the argument? Are there additional layers? I would like to kindly ask to keep replies away from views on the specific players in this specific press release. We'd just be reiterating our positions without convincing anyone.

More to the point, "technology is neither good, nor bad, nor neutral, it just exists". Ultimately all tools can be used for good or bad purposes and what matters is the people who wield them.

This is separate from the argument over whether MAD is philosophically good. MAD is not an argument about technology. "Peace through strength" does indeed require the occasional display of strength, to maintain deterrence. Good and bad (morals) are not the right frame to understand deterrence, rather emotions: fear, confidence, and security.

Solzhenitsyn can be read as either a humanist or an ethicist: either the bridgehead of good is sufficient to redeem everyone from war and morality demands pacifism, or all military doctrines must be submitted to independent review to check that we do not give the "unuprooted small corner of evil" oxygen. Crucially, these are both judgements about ourselves and not about the foes who seek to destroy us, who indeed consider themselves to have "the best of all hearts". In this sense, Solzhenitsyn contributes to the cycle of violence: if both sides are ethicists, and their ethical councils have different conclusions, the result is not just fundamentalism but a fundamentalism justified by ethical review.

Fear, anger, disgust are the ultimate drivers of conflict. Can we conquer them? Of course not, they are the base emotions, part of being human. But can there be a better way of handling them in geopolitics? Yes - if leaders are focused on helping not just themselves feel safe, but their enemies as well. This is the higher level beyond MAD - not mutual fear, but mutual security. This is why USAID was great foreign policy and cheap for its benefits. This is why weapons are sold to allies despite the fact that their interests may not be fully aligned with ours. Weapons are fundamental to security, which at the end of the day is a feeling and not a guarantee against attack or repercussions from an attack, and these feelings of security are what reduces the incidence and frequence of war.

Someone will find a reflexive material to put on the drone. Then you have a multi kw laser that hits randomly anywhere when intercepting drones.

Also I wonder why it is not common to run interception drones that automatically fly towards incoming drones and captures them mid air. Like a wasp is capturing other insects.

So pretty much like the iron dome but not with single use rockets but reusable drones instead.

Laser weapons appear to be advancing rapidly. Once we get to the single digit MW power range, MAD will deteriorate as the ICBM becomes a non-viable nuclear delivery mechanism.

What effect would that have? Will nukes start getting used in wars? Will we see deployment of multi ton NEFP[1] warheads that can strike targets with nuclear-propelled kinetics?
