You can be mad at America and ignore Iran's role if you want, but that doesn't lead you to anywhere productive. The United States like any country is an actor on the world stage that has interests and can take action to defend or assert those interests. If the world thinks this is a problem, they should have mediated between the United States and Iran and helped to prevent conflict. Instead they did next to nothing. War happened. Cue surprise and condemnation.

The entire world turning against American hedgemony is going to have "productive" repurcussions.

I think the world has had just about enough of wasting their time trying to mediate with your idiot of a president...

What was Iran's role? Defending themselves?
