Do you honestly think that we can just "deport" them overnight? How about a week? Or even a year?
They can mostly deport themselves. Dry up the job opportunities and they will either go back or starve.
We don't have to deport them all - all at once.
If we enforce existing laws, they will be forced to leave on their own.
No, it would take many years, but ICE putting on a public relations raid every 4 or 5 months and arresting a couple hundred illegals is a bad joke.
A little history from 1954: Operation Wetback
http://en.wikipedia.org/wiki/Operation_Wetback
Result: Operation Wetback deported approximately 80,000 Mexican nationals in the space of almost a year, although local INS officials claimed that an additional 500,000-700,000 had fled to Mexico before the campaign began.
The INS estimates rested on the claim that most undocumented people, fearing apprehension by the government, had voluntarily repatriated themselves before and during the operation.
