The most difficult part of the altercations between Iran and Israel is the matter of Jerusalem. In Iran a war against Israel is considered to be perpetual and will last until Jerusalem is in the hands of a military authority that has an Islamic nation in oversight of it.
Tehran’s leadership does not necessarily believe that Iran will be that nation. In recent history Iran’s Presidents have wanted it to be so. But cooler heads have prevailed and outright war has been avoided because it’s not believed that Jerusalem is their prize.
The local troubles in Jerusalem can be blamed to an extent on Iran, but they see that groups closer to Israel are more than capable of doing it themselves. Thus, they make attempts more along the lines of mainstream activity, such as moves to disrupt politics, influence society, and create trouble elsewhere.
