RE: the 2 million North Vietnamese Casualties included civilians.
Not true. Around 4 MILLION civilians were killed as a result of the war. In response to the idea that there were many other countries involved other than south vietnam is preposterous. Vietnam is much like Iraq is today: a handful of soldiers from allied countries.
The United States did not get its ass kicked The paris peace accords were signed and as a result the troops were taken withdrawn and american POWs were released. Nixon told the south vietnamese that he would send soldiers back in if the treaty was broken.
However, Nixon was fighting for his political life due to the watergate scandal and along with his resignation went an ally to south vietnam. President Ford didn't give a shit about vietnam and the North vietnamese knew this.
The weak North took control of the South and america shrugged. This wasn't because of an ass kicking, this was because america didn't think this was there war to fight and only did so because 'hawks' controlled the white house.
The North Vietnamese took control over the South, but only because the U.S allowed them to do so. Not because the U.S was bested.
