I'll have my doubts about the trading with the USSR. When we don't engage in trade, the dictators don't suffer, but the people do. Trade allows information to flow about the standard of living in other places. I have an number of issues with the other statements, but it would take a long time to write and I've got to go.
Poland was not liberated because of easy trade policies by the West, but by the courage of Lech Walesa and the Solidarity movement, along with the Catholic Church. South Africa’s apartheid regime was actually the target of trade restrictions by the West, not easy trade policies. People like you simply don’t understand what goes on in totalitarian countries. The people there may know very well that the outside world is freer and wealthier, but that does them no good. The govt. has all the guns, the gulags, and other weapons to stay in power. Trade simply entrenches the elite.
Once again, liberals supported sanctions and bans against South Africa.
