Not sure I fully understand your 1st question, as we were talking about Jews in Iran, not Israelis. But IDF did attack a weapons facility in Iran in February.
Israel has said it is ready to strike targets in Iran if diplomacy fails to rein in Iran's nuclear program or missile development.

Attacking a nation within its sovereign borders can constitute an act of war, no? And Iran already said they won't go to war with Israel. So there's that.
We can point fingers and say they started it going back many generations. What has that solved so far? Is it an act of war to use snipers to shoot protesters for walking close to a fence? Should all Palestinian civilians, children and babies included, be collectively punished for the Hamas attack?
Well, one thing is clear. You can't have peace through domination, subjugation, violence. All that creates is more extremism.
