US pulling out of Israel would be the most chaos inducing event in world history.
This is pure hyperbole. The most chaos you could get from this would be from Israel lobbing a nuke before getting taken out, which they already essentially threaten as it stands.
And what US rival is Israel going to find to replace it that has both the desire and means to do so? China and Russia don’t stand to benefit from that, even if they wanted to pump billions of dollars into Israel a year. They already have influence in the region with other powers the US is hostile to, like Iran. Israel is increasingly internationally discredited, so it’s not as though they’re going to get a great diplomatic boost. They already have nuclear weapons of their own and pretty developed intelligence apparatuses. What would be the point of taking on such a massive liability?
And let’s not forget that the region is in turmoil to begin with in large part because the US keeps intervening in it, as well as supporting Israel and other shitty governments in the region that are favorable to the US in some way. Israel itself destabilizes the region.
