The days of the small American military ended when the Shang brought down Yosemite Yards.  I was one of those new volunteers.  I remember they talked about the draft back then, but after seeing the number of people volunteering those talks ended real quick.  America may not be full of people that enjoy being in the military, but we are full of people perfectly happy to bust someone up if they come trolling in our neck of the woods.  And the Shang were real good trolls.
