How did communist vietnam dominate parts of southeast asia after the vietnam war?

Answer 1

The communist Vietnamese controlled parts of South East Asia through direct application of military force. They used insurgency tactics to undermine Laos and the Khmer Rouge took over in a military rebellion. The communists from the north murdered over 300,000 people and cause nearly a million to flee South Vietnam as boat people. The Khmer Rouge killed 3 million people to gain control. The communist Vietnamese then attacked the Khmer rouge and gained control of that country.

It should be known that the communist killed more people after the war during the peace forged by the American Democratic Party than all the soldiers that died in the war. Most of the Viet Gong (southern communist working for the north) that survived the war was killed by the north after it. Just a Stalin killed most of the partisans that fought the Nazi behind the line. The socialist philosophy is that if you are disloyal to your country even if helps them then the communist will kill you.

It also might be noted here that in the 15 years of the Vietnam war 1960-1975, the northern communist won only the battle in Saigon in 1975. And only after the DNC in Congress cut their gas and ammunition.
