"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"
Those are the words that are causing former Gangnam stylers round the country such agita.
Apparently, this was in 2004, two years after "a U.S. Army armored truck struck and killed two Korean schoolgirls" (according to Popdust, who I lifted the story off) and US-North Korean relationship was a little on the cold side.
Not an excuse for rampant anti-Americanism, or at least not if you wanna be a pop star in the US, and if it wasn't for the daughters, etc, line I don't see anything wrong with a strong political opinion.
My bet is the rest of the US disagrees and a heartfelt apology won't do it.
