No, an unilateral aggression is not a war.

I am not sure why you are operating on such a weird definition of "war" that because 1 thing happened 50+ years ago that changes whats happening now.

Just look at whats happening now. Iran is shooting missiles at all sorts of countries all over the place. (not just the US or israel). Its clearly in a war with a lot of groups right now. It is a silly handwave to pretend like a war isn't going on now, because of something that happened 50 years ago.

Its clearly not unilateral, given how many other countries, that are not the US, have had missiles shot at them by Iran.

As a similar example Russia invaded Ukraine. There is a war going on between them and Ukraine. And when there is a war, countries attack each other. "Who started it" doesn't change the fact that a war is happening.
