Vietnam summary

Hugh Hewitt sums it up well:

(The Vietnam War) was about stopping the Pol Pots and the "more civilized" variant of communism in the North. It was a noble effort. It failed for many reasons, but especially because of the domestic left in the United States, which slandered the front line soldiers as a tactic in the effort to withdraw America from Vietnam, and to settle the issue of moral superiority versus moral equivalence in the global contest then underway between freedom and totalitarianism.
America then and America now was and is undeniably the greatest force for good in the world. Its troops, then and now, fought and still fight to protect and defend the United States and to stop evil men, regimes, and ideologies from murdering millions of innocents. In those fights, there will be terrible tolls, and many innocents will die or be injured, but American armies fight wars - then and now - with more concern for the innocent and with more discipline and accountability than any armies in history.
