I am always intrigued to read an American's logic when it comes to government affairs. Europeans speak with largely one voice, America has gone mad, the leadership has thrown international law, domestic law and convention out of the window at the say so of a babbling idiot. This is largely England's position, we feel sorry for America and the sabotage on their respectability.
So I read your logic and try to picture how do you get to the position where it America is the good guy in this?
When we look at the invasions of others countries around the world in the last few decades, Vietnam, Venezuela, Nicaragua, Korea, Greenland. It is clear that America is an aggressor. What has Iran done? Funded some groups that don't like Israel, had a big fight with Iraq. There is no evidence that they would behave any worse than America or Israel.
On Day zero, America started an unprovoked, illegal in domestic law, war. Everything after that, Diego Garcia, Qatar, UAE, Straits of Hormuz was consequence, not evidence.
Do we like Iran's treatment of its citizens? Obviously not, they are at least as bad as ICE maybe even worse! But who cares? We in the west live in relative freedom, we are the minority, most countries oppress, to some degree, their citizens, should we invade them all? Of course not.
