I’m of two minds about this. The pictures and video of the attack on the US embassy in Baghdad was really disturbing. And digging deeper into the Iraqi politics was disturbing also. From what I understand, the rioters were representing the Iranian proxies (Shia I presume) trying to force a vote in the assembly and get the US out of the country.
Under this pretext and with the deaths of the US “contractors”, presumably at the hands, again, of the Iranian proxies... the President felt that the Iranians should pay a price. And their target certainly seemed (to us) to be appropriate. Supposedly he was the guy that orchestrated all of the proxies for Iran in the area. Our response wasn’t very diplomatic. It was pugnacious and probably felt to be “proportionate”.
The problem I see is that the Iranians are not helpless. They are not powerless. They are, in fact, very capable of exacting significant damage to the US and our citizens and interests. I doubt you will see much direct confrontation between US forces and the Revolutionary Guard. What you will probably see is repeated attacks against our citizens and soldiers in the Middle East and maybe here in North America. Assassination attempts. Attacks on our infrastructure. IT attacks. Not all at once. I expect it will be several things over several years. Sneaky stuff.
My take: our President and the administration decided that the best response to the situation would be to exact a price. Iran will exact a price, too.
It’s impossible to say, at this point, whether the prices that are paid are “worth it”.
