Actually, we won't have to go back to Mexico; Mexico is coming to us.
Saturday, at a Catholic church down the road a way, they said a funeral mass for a young man who was killed while serving with the Army in Iraq.
Thing is, this boy (the same age as my son) wasn't even an "American." He was a resident alien who had signed up so that he could become a citizen. (My own grandfather did the same thing back in the "Great War.") He didn't live to become a citizen, but he'll be granted posthumous citizenship and his family (many of whom only attended the mass after intervention by our congressman to get them across the border) will be eligible to become citizens more quickly.
A lot of us don't value our citizenship, but to some people, it's worth everything. The country will be better off with more of them.
