A Fox Business commentator is stunned that most Americans oppose the war on Iran, exposing a wide gap between hawkish pundits and public mood.

• Larry Kudlow called opposition to the war "Nazi-like" and compared Iran to a bigger threat than Al-Qaeda, despite Iran not attacking the US.
• Polls show most Americans, including a growing share of Republicans, do not support the war or Israel's actions in Gaza.
• Critics say the war violates the US Constitution, the War Powers Act, and international law since Iran did not threaten the US.
• Public opinion has shifted as people see the scale of destruction in Gaza and judge it as going far beyond self-defense.
• The split between Washington pundits and regular voters is widening on Middle East policy.

Outlook: Support for the Iran war and for Israel's Gaza campaign will likely keep falling, putting pressure on US politicians from both parties.
