Yeah, W's a globalist...you have been keeping up with events for the last, oh, 4 years haven't you? *bangs head on wall*
The fact is there is little that can be done when the most powerful, richest, freest nation in the world lives next to a has-been/never-been kleptocracy. We can't keep them out without killing them, and we ain't killing them, despite what some folks want. That isn't American, it isn't even rational. It most certainly isn't Christian.
The best thing we can do is stop what we can short of going into "iron curtain" mode and exert pressure to bring Mexico up to par with at least Mississippi. That's all the President reasonably be expected to do.
Then, by your "logic," we must simply let them in, let them vote and let them have this country with no fight and no struggle whatsoever. Just hand over the keys to your house to whatever illegal comes by and demands it. Nice thinking.
