My first suspect was the Chinese! They'll do just about anything to be the world's top super power!
I never could figure what the Russians could really gain by interfering in our affairs but I suppose there are a few things they would like to get into to bring back the old Soviet sphere of influence.
India? Our relations with them has been spotty over the years and I wish we would get closer to them and dump sending money and aid to Pakistan. Which plays both sides of the fence with the money we send them. India could be a true ally!
China will always be for China first no matter what any other nation says or does. They waste billions trying to buy all this influence while not much caring for their own people.
