Iran would condemn, but probably do something more about it. Certainly they'd increase the funding they give to Hamas and Hezbollah, two internationally recognized terrorist organizations that exist to try to annihilate Israel. One reason Israel is so concerned about everything Iran does is because it does do shady things like that.
But Iran does have the military might to attack Israel, and it's not like they don't have a way since both Iraq and Syria will allow them to go through without raising a fuss about it(Jordan, though, wouldn't, so it's not the most direct route). Israel has to be very careful about when they attack, since Iran has sheer numbers on their side.
After that Israel fighters can not return to their country because Israel involved by Iran.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
