I think you are right. If Mr. Steyn is wrong and we are surprised to see the Europeans physically resist the Islamofascists' plans to take over the Continent, then the U.S. would have no choice but to immediately build up a larger military force to ready ourselves, and, alas, help out the Europeans again. I have no problem with helping the U.K. (that country fights) but France, Belgium, etc. Yuck.
I myself see nothing wrong with every able male conscripted to serve his country in some capacity. Real pacifists can serve as medics or in some other non-combat capacity.
What about every able female? Maybe the able females serving in Congress will push to do the right thing if Draft legislation comes up for debate?
