Yeah, the political leadership is chilly at best and ugly at worst. But that has little direct relationship with numbers of people lost invading the place. Yugoslavia and South Korea both have been hosts; try correlating that with effectiveness of military defense historically, and again with perceived openness and democratic measures (hint: South Korea is not exactly a democratic paradise when you look closely, even if it's nothing like the North).
And it doesn't necessarily follow that political leadership being crude and suppressive to their own people, makes for a bad place to visit for the experience and cultural exchange. Whether you think that helps the right people inside, is another question.
