This happened earlier this month where a US Marine is attacked by pro-Palestinian thugs because he supported Israel:
A national march for Gaza took place in front of the White House. A pro-Israeli counter-protester (U.S. Marine and Iraq War veteran Manny Vega) was standing on 16th and H Streets with Israeli and American flags. Vega was approached by an Arab who began engaging in a very productive conversation with him. However, as more pro-Palestinian protesters marched by them, some engaged in violent acts against him. (This is where the video begins recording.) He was punched, pulled, kicked, and even spat on.
Note from videographer:
Some were asking why Manny reacted strongly in the first few seconds of the video. It’s because he was already being attacked and driven away by some protesters; I started recording moments afterward so the video doesn’t show the initial confrontation.
