I think a lot of is rooted in American idea of colonialism, "Manifest Destiny", general Ann Rand style brain poisoning.

They see indigenous people as sub-human who aren't using the land they occupy properly. As such they believe its their right to take it from them cause they aren't "doing it right". Its our right to take from those we see as lesser. We have been doing in Africa and South America and much of Asia for decades. The American people see pretty much every non-western European nation as barbarians in the rhetorical sense. Uncultured savages who need to be either need to be broken or buried.

If some other people have what we want and they don't look some dude from the state of Maine we feel totally okay using every T-800 we have in our vast armory. Also no amount of capital vacuumed up for working people or the blood of the youth is too much to get it.

I also don't think people understand that Israel is client state, I also don't think most people don't understand what client state even is. Ukraine is my go-to example. Every single coin and bullet we have was sent to them no questions asked, and we will do the same thing to Israel. We will give them War Machine power-suits to destroy residential buildings and parks indiscriminately.

I really don't think people understand foreign policy at all. Nor understand that America is an empire and doing empire shit is bad. Pretty much every comfortable in the US is a warhawk the moment they understand its brown people or "The Reds".
