Palin says it’s not practical to deport them. Then what?
All the illegals could be sent to the buffer state ~ which would be totally free of interference from Mexico city.
We'd build our wall on what is now the Mexican side of the border.
All passenger traffic from the South to the US would have to land somewhere in the buffer state for passenger evaluation and clearance. People who we imagine might overstay a visa will have to stay there, or go back home.
NOTE: 12 to 30 million people can be caught and sent to this area in about 6 months time for just a few billion bucks. Ain't no thang, and it can be done quite humanely.
JUST WHO ARE THESE PEOPLE who imagine we'd only do this by telling them to pack a bag and hit the road South on foot?
Good Lord, their nightmares must be something else.
