I wonder if this passaage from Bush in that last Presidential Debate might have been the last straw for these young soldiers:

I remember going on an airplane in Bangor, Maine, to say thanks to the reservists and Guard that were headed overseas from Tennessee and North Carolina, Georgia. Some of them had been there before.

The people I talked to their spirits were high. They didn't view their service as a back-door draft. They viewed their service as an opportunity to serve their country.
