GANGAM STYLE rapper PSY's BIG hate for the United States of America has surfaced.

The worldwide sensation South Korean rapper PSY, aka Park Jae-sang  whose “Gangam Style has been downloaded 3 million times on iTunes and  is the most-viewed video in YouTube history, netting  him more than $8 million is under fire, The Hollywood Reporter revealed.

But now as he makes the internet meme roundup and has guested on Ellen and Today, Psy is now going to answerable to past un-American rants.

At a 2002 concert staged in 37,000 U.S. troops deployed on the Korean Peninsula, Mediate reported, Psy took to the stage in gold face paint and a glittery red outfit.

He then lifted a model U.S. tank above his head before shattering it to pieces on the ground.

Reportedly, his staging was a response to the death of two Korean school girls, killed in an accident with a US military vehicle, according to Korean website BusanHaps.com.

Two years later, in 2004, after a South Korean missionary was executed in Iraq — a payback killing for Korea’s support of U.S. war with Iraq, PSY flamed the fans of hate at a protest concert.

On his song “Dear American” Psy rapped:  "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."
