Eisenhower’s deportation wasn’t instant, but it was apparent to all that were here illegally that their time would come shortly. About half of the total that left did so on their own.
What has been missing is a respect for the law from the likes of Clinton, Dubya and Obama. Every foreign national wanting to ignore our laws got the message loud and clear. Dubya and Obama being the worst, both siding with the illegals and pushing for amnesty.
All that any President has to do is start removing people one at a time. Any hard cases are tough luck for those who gave themselves permission to break the law. Any problems they or their children encounter is due to their own choosing, their own disrespect for the law, and it doesn’t matter one bit whether Obama or Dubya or any other treason lobby hack was cheering for them and against the American people who have had to watch our own culture and way of life get washed away in the flood.
That “missing respect for the law” of which you speak is not turned around so easily these days. It is the result of linguistic and philosophical forces aided not only by technology but also by a studied disregard for objective truth and virtue as espoused by the practitioners of public education. The nature of man, the nature of marriage and family, the nature of God - all of these have been steadily eroded in our midst. We do ourselves a disservice in treating the illegal alien problem as needing an “either/or” remedy: either deport them all now or grant them amnesty and all benefits now.
