1. The US "intervention" in WW2 was fully justified because the US was attacked. It's also justified to help another country that is attacked, for example the US campaign against Iraq during the First Gulf war was justified. Both were defensive actions, not wars of aggression. Preventive wars are also wars of aggression, though, and classified as such by international law. There are fairly direct equivalents of all of this in regular penal law.

2. I never claimed I cannot be mistaken. It's best to focus on arguments, not persons.

> Great. Then no war is acceptable.

War has at least two sides (often more). A war of aggression is never acceptable. You've got that right. That's also how it's viewed in international law. Defending against a war of aggression is always acceptable. Helping someone defend against a war of aggression is also acceptable. There is a third category, a military intervention by a broad alliance legitimized by some international body. That is in the "it depends" category but plays no role here. Now countries that start wars of aggression know all that and therefore often argue they're just defending themselves. I'm stating that this is a pretense and not a correct justification in this particular case of the US attacking Iran. I'm not planning to go into the details why this is the case, it is obvious enough anyway. Just to make this clear.

I have no comments about the rest of your comment, which, frankly speaking, to me mostly sounds like self-aggrandizing remarks. I was mostly referring to how established international law looks at the matter and your personal views interest me less. Have a good day!
