PSY has been involved in several anti-American protest performances. According to Mediaite.com he smashed a model U.S. tank while onstage in 2002 to oppose 37,000 U.S. troops that descended on the Korean Peninsula.
PSY published a song titled "Dear American" with the following lyrics:
“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,” he raps.
