Obviously in that scenario North Korea would be doing so to prevent anyone from being president, that is quite different then the case of Barack Obama and the four countries that can claim him as a citizen (Britain, Kenya, Indonesia, and the United States).
At the time of his birth and throughout most of his life, each of these countries had a policy of no dual citizenship’s, which leads me to wonder why when he feels he is a citizen of the world and has said so, (in his speech in Berlin) can he also claim to meet the requirements of the presidency as laid out in the US constitution.
First and foremost is the requirement of natural born citizenry with no other allegiances to any other country, Obama clearly fails that test, the best example of that is that he has campaigned in Kenya on the behalf of his distant cousin in the Kenyan election for the presidency there. Under US law such actions are illegal, yet it did not slow down Obama in the least.
I can only assume that by his actions he places himself above US law and the Constitution itself, since he fails to abide by our laws and the very framework of our government.
