To be honest, I do not like that strategy. In fact, I do not like how the Iranians are fighting this missile war.
They should be hitting Israel with everything they got and do it twice as hard.
Wiping out Americans bases are a goal which they have done an excellent job.
Still, I would believe the main goal is to get Israel.
Because if Iran wipes out Americans bases, Israel is still there. They should try harder to wipe out Israel. That is brutal but I do not think they are trying hard enough.
The problem with trying to convince the Arabs not to have the Americans comeback, the Iranian will need a long war to traumatize the Arab populations and leadership that US bases are ultimately not in their interests. In fact, it may take another war for that to sink in.
So, I do not think Iran has hit Israel hard enough, and not really hitting Arab states much at all. The big success is the bases.
But we are not allowed to speculate if any outside help was used, so the self-censorship continues.
