I'm not really sure if it's any political issue that's causing the lack of promotion, but i'm pretty sure that people are referring to the current Dokdo/Takeshima Island dispute. Things have gotten pretty nasty over it and KARA were even asked about it, but smartly dodged the question (which did upset some people since they didn't take sides). A lot of us on the outside really don't understand why two countries would let a tiny island continue to divide them. There are a lot worse issues that have gone on with Japan and Korea in the past, and I guess this only helps to fan those flames.
