Massive anti-war protests broke out in US cities like New York, Washington DC, Boston, and Chicago following US airstrikes on Iran’s nuclear sites—Fordow, Natanz, and Esfahan—under Operation Midnight Hammer.

Demonstrators carried banners saying “No US-Israel war on Iran” and criticized both the US and Israel’s role in escalating tensions.

Social media was flooded with visuals of the protests, with many urging the Trump-led administration to halt support for Israel. Demonstrators also condemned Israel's actions in Gaza.

In response to the heightened tensions, US cities increased security, especially near cultural and diplomatic sites. Meanwhile, netizens questioned whether the protestors had legal permits, sparking debate online. The NYPD confirmed enhanced deployment “out of an abundance of caution.”
