In addition to the other valid points presented, here's one that just hit me: Anonymous speaks English as their primary language. Of course Anonymous is made up of people from across the globe, but are there enough of them who a) speak/read Korean, b) care about North Korean politics and c) have the abilities to do something about it? Probably not. There are apparently enough English speakers that care about the politics of the English-speaking world that have the ability to do something about it, though. Maybe this is a function of the distinct cultures involved, maybe it is a function of socioeconomic status, maybe it is a coincidence (doubtful), but no matter what caused it, the lingua franca of Anonymous is English. Their actions primarily affect the English-speaking world because the members of Anonymous who meet the criteria I listed above stand to benefit from it.
