China and Russia are playing nice for the United Nations and endorsing tougher sanctions on North Korea as they continue to adamantly refuse to destruct their weapons of mass destruction. However, the prospect of what could come is incredibly frightening:
Both China and Russia are longstanding allies of North Korea, though relations have tensed recently. China continues to aid and support North Korea. Let's suppose North Korea decides they want the peninsula, as dictators do tend to get greedy and decide to take over the world. Knowing that they are already on the verge of having the crap bombed out of them by the big ol' boys, they decide to take out South Korea. The big boys come to the aid of South Korea, and North Korea is forced to rely on Russia and China.
China, whose population far outranks the big ol boys' anyway, decides to use another weapon at their disposal: they call in the billions of dollars on loan to the United States. Due immediately in full plus interest. We, the patriotic Americans that we are start counting our pennies, selling off our government owned Hummers, yachts, jets and mansions, and realize wait a second... why are we giving up our hard earned, albeit not entirely paid off luxuries for a few people an ocean away.
So we tell China, hey you know we'll back off if you don't make us pay up and let the UN take care of things. China agrees- the damage is done to South Korea and the North Koreans have spread oppression further in the world.
Not the United States of America I want to be a part of.
