The Iran war has gone badly enough that even its backers are uneasy, but the striking part is that almost no one in US politics is objecting.

• The war has produced consequences bad enough to raise doubts it was ever worth starting.
• Trump likely knew the risks going in and went ahead anyway.
• There have been no anti-war protests, in a country that normally produces them fast.
• Democratic leaders like Chuck Schumer backed regime change in Iran too, differing only on how it should have been done.
• That leaves almost no organized opposition to the war inside American politics.

Outlook: With both parties committed to the same goal, expect the Iran policy to continue with little domestic pushback.
