The Armed Forces: Presidential Gofers?

Well as if our National Guard has been through enough in Iraq, the preliminary groundwork is being set forth for the possibility of returning troops to be sent to assist border patrol agents on the Mexico/U.S. border. Although the current administration is seeking other alternative ideas to secure the home front, sending our G.I.'s seems inevitable until a more permanent solution is found. I guess hiring and training more agents, as well as increasing the border patrol budget, would just be too far out the question because it just employs too much common sense. Perhaps we should take a lesson from the Chinese, and invest in a great wall of our own. Sure the initial investment is rather large, but once it's built it requires minimal maintenance and would give the overtaxed border patrol a fighting chance. Why not?
