The clerics and politicians in Iran use the US as a great big boogeyman to drum up political support, but until recently most of the regular people just didn't care about the regular people in the US. Same with the people in Iraq, or Afghanistan, or Syria, or Yemen, or Somalia, or Pakistan, or ... If they do have an opinion about the US, its probably that they mostly wish we'd stop bombing their homes and just leave them alone.

But, it makes the defense industry a whole lot a money, and its good for getting Republicans elected. But helping US citizens, some of which might have gasp brown skin, that doesn't make any defense contractors any money at all! /s
