US public opinion is turning sharply against Netanyahu, which is bad for Israel's standing but reflects growing anger over the war in Gaza.

• New York Mayor Mamdani is calling Netanyahu a war criminal and demanding the federal government enforce the ICC arrest warrant against him.
• Mamdani admits the city has no legal power to arrest Netanyahu, so it stays a symbolic stand rather than a real threat.
• Netanyahu says he will visit New York anyway for the UN General Assembly in September, accusing Mamdani of stoking hate.
• A new poll shows half of Americans want Netanyahu arrested on arrival, with support far higher among Democrats and young people.
• Even many religious American Jews are split, with a quarter saying Israel has committed genocide in Gaza.

Outlook: The generational shift against Israel is likely to keep growing, straining the US-Israel alliance over time.
