Strawman argument. The Khmer Rouge were not Vietnamese. Among others, the Khmer Rouge specifically targetted Cambodians who were ethnically Vietnamese. FYI, the Vietnamese are the ones who put an end to the Khmer Rouge genocide in Cambodia.
Again, please provide documented evidence, from a non-Christian source, of people currently being sent to re-education camps in Vietnam simply for being Christian.
Vietnamese Communists, with the exception of a small handful of the oldest bosses are not ideological Communists these days. The government of Viet Nam more resembles a mafia organization with a large capable army. In fact, everyone in the government wants to do everything they can to make the Americans protect Viet Nam short of the point at which they lose their jobs. Sooner or later they will lose their jobs. We do need to keep the pressure on. Vietnamese Communists fear China far more than they crave collectivization. The only useful thing Bill Clinton did was open up to Viet Nam. He did it for all the wrong reasons but he did it and the rapid changes taking place in that country now are due to American influence and pressure that were muffled by the barriers before that. All that does not translate into Cuban. Not before the Castros and their whole generation is dead.
