This is bad news for anyone hoping Washington would act as a check on presidential war powers, since even a sympathetic ally like Tucker Carlson says Trump brushed off the risks of attacking Iran.

• Tucker Carlson says he met Trump in the Oval Office days before the US struck Iran, trying to talk him out of it, the way Charlie Kirk reportedly also tried.
• Carlson says Trump agreed the war was being pushed by Israel to weaken Iran, sideline Gulf rival states, and push US troops out of the Middle East, but waved off the danger by saying "in the end, we all die anyway."
• Carlson has separately said Trump should be removed from office over his threats to use nuclear weapons against Iran, calling it a stance that should trigger the 25th Amendment.
• No one in Congress or Trump's own cabinet has moved to challenge him, despite a public account of the president downplaying nuclear risk and mass casualties.

Outlook: Expect continued pressure and criticism from commentators like Carlson, but little sign that Congress or the cabinet will act to restrain Trump on Iran or nuclear policy.
