The thing getting overlooked is all of the recent moves by Trump all lead back to China. Venezuela, Cuba, now Iran. These are all tentacles of China. The aggression against these 3 countries is not a coincidence. It’s a concerted and indirect attack on China in an attempt to weaken their subsidiaries. In the eyes of this administration, this is unpleasant, but necessary housekeeping that should have been done decades ago but no one was willing to spend the political capital to do it.

In Iran, Trump was clearly hoping (and verbally requested) the same thing you say about Sadam. I think we actually do know how unpopular the regime is, the mass protests demonstrated that. But the religious hardliners are the ones with the guns. And they clearly aren’t afraid to use them. So while there was some momentum, after everyone got gunned down in the streets by the IRGC it quickly deflated. So asking unarmed protesters to step up again is kind of big ask, without any material support.
