KoreaSo I'll vote Iran and North Korea. Biggest potential threats are China, Pakistan and Russia. None of them are our enemy per say, put Pakistan could turn quickly and China and Russia should not be discounted in entering future conflicts on the opposite end of the seesaw. I would enter the EU but unless one or more of the countries became unstable, I only see them as a moderate economic threat. But if Europe is making money, we probably are, too.
