When its child killing policies result in the breakup of China into its component parts, they'll fall back to their rightful place of poverty and obscurity on the list of prosperous nations.
I would like to see us cease all normal trade relations with China, a disgusting totalitarian state. And if that happened to trigger enough internal dissent to dissolve the PRC, all the better. China's government is the enemy of its people, and I would very much like to see it disappear from among the governments of this world.
China's history would lead one to think that another divided period could occur next; however, China is prosperous, and I myself cannot think of an instance where a large and prosperous totalitarian state anywhere in the world has fallen to internal forces to be replaced by more representative government.
