I think they’re asking from the context of it being a military vessel being deployed to a relatively hot zone.

That is an direct act of war against near peer level opponent. They can't just roll over. But must respond in kind and cause at least similar or larger damage. Say sinking a aircraft carrier or a few.

Because china has the means to reply. It's one thing to bully countries that can't defend themselves like Venezuela, Cuba or Iran, it's another one to do the same with the factory of the world

It could backfire in a way that ends American actions like the one the Chinese have pulled there ballistic missled arm chair up to watch the action more closely. The recent embarasment of european tech by chinese tech in pakistan india scuffle, is a hint at what are otherwise unknown Chinese missle capabilities, ie the two OTHER ships in the flotilla, there will of course be many oilers , tenders, and whatnot joining up, complicating things further. Plus given that China got this hardware on site in 10 days, is a message all it's own.

Ehm, geez, I don't know.. World war three ?

Israel is doing whatever it takes to start it, we must resist.
