Speaking to a joint meeting of Congress, Israeli Prime Minister Benjamin Netanyahu on Wednesday made the case for why the U.S. must support the Jewish state as it fights Hamas and other Iranian-backed militias: “If you remember one thing from this speech, remember this: Our enemies are your enemies, our fight is your fight, and our victory is your victory,” Netanyahu said to a standing ovation in the House chamber.

But outside, in the streets of Washington, D.C., thousands of protesters, some of them violent, sought to make their own case for why Netanyahu is a war criminal who should be charged with genocide over Israel’s retaliation against Hamas in the Gaza Strip. They did this by burning an effigy of Netanyahu outside the historic Union Station, just blocks away from the Capitol, and burning American flags. The demonstrators, dozens of whom were arrested, clashed with police and vandalized monuments.
