That's not true, artbrooks. The evacuation of US forces from Saigon was ongoing right up until the day the city fell to the North Vietnamese.

The war was not winnable, and millions of Vietnamese, Laotians, and Cambodians had to be killed before the US could learn this lesson. The Vietnam war was never about the spread of Communism.

Ho Chi Minh and his guerillas were trained and funded by the US Office of Strategic Services during WWII. After the war, while the French and Chinese were fighting over who would have Vietnam, Ho Chi Minh repeatedly pleaded with the US government to help them gain their independence. We refused and sided with the colonialists. The Vietnam war was a war of independence from colonialism. Had we been willing to help the Vietnamese win their independence, the Vietnam war would never have happened. But nevertheless, as a war of independence from colonialism, terms like "handing a victory" to anyone at all are not really relevant - the war was unwinnable.

We will find that Iraq and Afghanistan will provide us with similar lessons as Vietnam did. As with our foolish belief that the Vietnam war was about Communism, our rhetoric about the Iraq war, as well as the war in Afghanistan, that those wars are about the spread of radical Islam, is just as foolish. They are wars in which imperialist powers of the West are trying to impose their will upon the peoples of the Middle East. The peoples of the Middle East will fight this until we bankrupt ourselves so utterly that we, as an imperialist power, will go the way of the Soviet Union (as it appears that we are well on our way to doing).
