Vietnam WAS a successful application of the containment doctrine. It did stop the monolithic communist movement long enough for the Chinese and Soviets to have their falling out. Had those sacrifices not been made other dominos would have fallen in the early and mid sixties. It cost us 56,000 American boys and the horrors the locals lived through but the Comintern was contained for a crucial decade. Had the communists rolled on throughout Indochina after the French left who knows if they would have been containable until Reagan came onto the scene. It’s just a damned disgrace that Vietnam ended the way it did.
That is not true and was the original Domino Theory BS to justify the war that never should have been fought. Read the two books by Col. Fletcher Prouty and you will learn a lot of history about the war you never knew. Basically it was a CIA operation all the way.
You really think the Gulf of Tonkin incident was an accident?
The funny thing is today Vietnam has a market economy, although the government is still authoritarian. But it’s not more authoritarian, than say, Singapore.
