You don't know how weak and corrupt the Iranian (Islamic Republic) army is. If the US really wanted to end them it wouldn't take more than 48 hours. And that would be good for the whole world, specially for the Iranian people. But the globalist don't want this. They want a destabilizing country in that region cause it's good for their bottom line. There is this false narrative in the west that the Islamic Republic is somehow a strong formidable country that a war with it would be disastrous. Islamic Republic is weak and has almost no support among the Iranians.
