A nation fighting for its survival doesn't randomly escalate by attacking a much bigger enemy.

Instead, we frequently see it from dictators with a delusion of grandeur.

Iran attacked Israel directly twice, they are the ones which both escalated and miscalculated their position in the region.

"randomly escalate"?

You DO realize how absurd this is. Iran isn't exactly subtle about its hatred for Israel and desire to destroy it and funding of the "Axis of Resistance".
