Could it be the travesty of the Vietnam War, to make the world safe for democracy? Vietnam is now a communist country and a tourist destination where Americans can crawl in the tunnels where servicemen died. Democracy is pretty safe, except for the likes of Donald Trump. Or it could be the twenty-year debacle in Afghanistan. A better question is, "Why did the US end the draft?' Answer to shut up the war protesters so we can occupy places like Afghanistan and wage war for 20 years with hardly a whimper of protest.
