You keep assuming the Arab states were going to attack when there is no evidence of that. It’s just the fact that Israel felt threatened, when every country feels threatened. The way nations form is the basic narrative that there is an enemy out there threatening you and you have to band together to take on that enemy. Even countries as secure as the u.s. will contrive threats from China or the cartels to point to an enemy.

Again I’m not going to argue which party fealt more threatened because that’s a subjective experience. There are countries that are just as threatened as Israel was and they don’t attack.

All the points you just made could be made for enemies of the u.s. like Iran, north Korea and Cuba. North Korea also suffered a horrific bombing campaign by a country on there border and suffers far more from economic sanctions then Israel ever did when the straits were closed. The embargo on Cuba has repeatedly been called out as against international law. If Cuba or north Korea demanded an end to sanctions or it would be war, and then the u.s. poured troops in to surround them on there borders would it be right for them to launch a first strike against Seoul or Florida?

No you’d probably say they made a threat to the u.s. with that ultimatum and the u.s. deploying troops was a valid response to that threat. Any sort of ultimatum that involves war should be considered a threat and an escalation. You don’t get a pass because you were treated horribly before.
