USA tried to establish themselves in those lands also to prevent future terror attacks, which I think they did. It's questionable if it was worth it or the right thing to do, but in the meantime, you guys in the USA didn't have a single terror attack afterwards, or? (I can't remember to be honest)
What would a single Israel's strike on the 8th of October etc have done? They got 100+ hostages, some are still there btw after 2 years, and there is proof that the civilians knew about it and actually supported it.
People still support Hamas and still believe they will win. Without mentioning that those people (the civilians, yes) supported that s** that "Hamas" had done on the 7th of October - there is plenty of evidence for it.
