What would Vietnam look like if the U.S. had completed the job? What would make it so much better off? It developed into a secure, free nation, which was the sole reason for the occupation. Would the U.S. have remained in Vietnam to help it even after it was self-sufficient? Anyway, If we cannot sustain military action or another severe threat arises elsewhere, we may be forced to run against our will.

More significantly regarding hit-and-run wars, Gen. Wesley Clark(4-star retired general) wrote in his memoir A Time To Lead that he visited the pentagon and a classified memo was shown to him that indicated the administration planned to invade 7 countries in 5 years, one by one, in what can only be described as a hit-and-run strategy. He didn't read the memo, but it was a senior general that was indicating the strategy.

It's interesting, but of course it's clear why that strategy wasn't carried out. It presumed that democratic governments could be installed virtually overnight. It's still interesting that the same tactics used by Bill Clinton were considered.
