At a 2002 concert staged in opposition to 37,000 U.S. troops stationed on the Korean Peninsula, Mediaite reports, PSY took to the stage in gold-face paint and a glittery red outfit, then lifted a model U.S. tank over his head before smashing it to pieces on the ground. The performance was a response to the death of two Korean schoolgirls killed in an accident with an American military vehicle, according to Korean website BusanHaps.com.

Then, two years later, a South Korean missionary was executed in Iraq -- a revenge killing for the country's support of the U.S. war in Iraq. During a protest concert, PSY rapped on the song "Dear American," "Kill those f---ing Yankees who have been torturing Iraqi captives/Kill those f---ing Yankees who ordered them to torture/Kill their daughters, mothers, daughters-in-law and fathers/Kill them all slowly and painfully."
