A televised clash over the US war with Iran turned into a broader fight about whether backing Israel counts as loyalty to America, and it went badly for the pro-war side.

• The war's stated goals — regime change, ending Iran's nuclear program, cutting off Hezbollah, reopening the Strait of Hormuz — have not been met.
• The Strait of Hormuz was not a problem before the fighting started; now it is, and the global economy is paying for it.
• Trump's justifications for staying in the war, including the claim Iran was weeks from a bomb, are unbacked.
• Calling every critic of Israel an anti-Semite has stopped working, and is fueling the backlash it claims to fight.
• Dershowitz has said he switched parties over Israel alone, which critics read as putting one foreign country above every American issue.

Outlook: Public support for the Iran war looks set to keep sliding as the goals stay unmet and the Hormuz disruption keeps squeezing energy markets.
