Psy is internationally known and a YouTube sensation thanks to his hit “Gangnam Style.” But recent images revealed that he has an alleged anti-American past.

Mediaite reports that during a 2004 performance against 37,000 troops in South Korea, Psy showed his anger by destroying a camouflaged American tank onstage. In another incident dating back to 2002, he expressed more anti-sentiments in a song called “Dear American.” The Huffington Post dug up the lyrics from The Hollywood Reporter, which you can check out below:

Kill those fucking Yankees who have been torturing Iraqi captives
Kill those fucking Yankees who ordered them to torture
Kill their daughters, mothers, daughters-in-law and fathers
Kill them all slowly and painfully

Although news outlets everywhere covered the singer’s anti-American rallies during the Iraq War, he has issued a official apology through his publicist Matthew Hiltzik. Many Americans love Psy, so hopefully his words will be accepted with open arms.

“As a proud South Korean who was educated in the United States and lived there for a very significant part of my life, I understand the sacrifices American servicemen and women have made to protect freedom and democracy in my country and around the world. The song I featured on in question from eight years ago—was part of a deeply emotional reaction to the war in Iraq and the killing of two Korean schoolgirls that was part of the overall antiwar sentiment shared by others around the world at that time. While I’m grateful for the freedom to express one’s self, I’ve learned there are limits to what language is appropriate and I’m deeply sorry for how these lyrics could be interpreted. I will forever be sorry for any pain I have caused by those words.

“I have been honored to perform in front of American soldiers in recent months—including an appearance on the Jay Leno show specifically for them- and I hope they and all Americans can accept my apology. While it’s important that we express our opinions, I deeply regret the inflammatory and inappropriate language I used to do so. In my music, I try to give people a release, a reason to smile. I have learned that thru music, our universal language we can all come together as a culture of humanity and I hope that you will accept my apology.”
