A "one world government" isn't going to solve that. There are too many different ideas about the proper was to organize a society that are in conflict. There isn't really any way to peacefully accommodate those conflicting visions in a single country with a single vision.
You also put too much stock in cointelpro. That was long ago, and had limited reach.
As to Mr. Wong and Mr. Ming, there is a very good chance that even today Mr. Wong hates the idea of Mr. Ming due to traditional grievances between their peoples, especially over what happened in the 1930s and 1940s.
There are too few honest and honorable "peace" activists. In 1990 when Saddam Hussein invaded Kuwait there were few if any protests in Europe. There were many protests when the US organized a coalition and sought UN assistance in removing Saddam from Kuwait. In the 1980s the "peace" movement in Europe danced to Moscow's tune.
