rangel's motive:
If republicans, and more importantly, republican donators - who support the war but keep their kids home - suddenly have to kiss their children goodbye to send them to war, they will reconsider their support for this war.
The draft killed vietnam. It could do the same for iraq. Anti-war people are just too dumb to realize it. The moment every senator gets a call from his son saying grandson is heading to Baghdad, the senators will vote to cut war funding and iraq ends.
(note to all: We will be in Iraq for 5 to 7 more years. We are installing an oil pipeline in iraq, afghan, and eventually, iran. So it's all a moot point to argue anyway)
