It is not necessarily pro-regime. People are fired up when a foreign nation attacks their homeland. They fight to protect their homes, then later deal with the politics.
What is Trump's payoff? If it were about Iran's nukes. He threw that away long ago. Obama had a deal that kept Iran from nukes. Trump was supposedly near a similar deal. Yet he launched a sneak attack instead.
Trump makes decisions on his own for reasons only a person s twisted and weird could understand. Don't look for logic and planning. He is not capable of that.
