One of these "things" is that the "mercenary soldiers" he is describing are Americans, and not only that, but some of our best young citizens. Not a gang of bloodthirsty killers, or a Foreign Legion that will do ANYTHING it is caommanded to do (look up the FFL record in Algeria- I don't recommend looking at many of the pictures of their victims).
Any Army can be abused and misued- as I think the Army was by Clinton. It makes no real difference if the soldiers are conscripts or volunteers. "Scuttlebutt" about a military coup was just that- morose griping by an Officer Corps that had been betrayed. But I was in a Ranger Battalion around then, and there is no way on God's green Earth that we would have accepted any order to overthrow civilian authority. These conspiracies exist in the minds of folks on the lunatic fringe. Also, I might point out that Rep. Rangel is not serious about resuming the draft (or UMT, either)- he just wants to generate more war protests by raising this dire possibility. A typical Commie-Democrat move.
