I read that Diem was a good Catholic leader, he allowed the Buddhist to practice, and our gov fell for the false VC propaganda like the monk ѕυιcιdєs. .

Yes, Ho Chi Minh considered him the one able South Vietnamese opponent. He marvelled at the stupidity of the South Vietnamese military and Pres Kennedy in overthrowing his one worthwhile opponent. The South Vietnamese leaders who followed were weak, transient men. LBJ was right to oppose it and regret the overthrow. Ngo Diem burned with a love of the Faith. His brother, Archbishop Ngo Diem Thuc, made an effort to give effect to the President's love of the Faith. Perhaps Archbishop could have been more cautious like Archbishop Lefebvre, but likely +Thuc could not swallow the sickening potion of Vatican II in the hope of a future restoration. JFK threw away the Vietnam War, and the Catholics of Vietnam for the sake of appeasing some worthless, hardline Buddhist generals in Vietnam, and a horde of Liberal, anti-Catholic American journalists.
