How recent do you mean? What are the illegal aliens who are a few months or even years short of amnesty going to do? Do you think they're going home, or will they just stay here, living as before, since they know there is little chance they will be caught AND deported.
Two or Three years? I can't see millions of Mexicans being lined up and deported. Do you know how the media would twist things and make President Bush look like Hitler. Get the criminals out and get rid of the baby bill, then build a wall/fence. I believe our technology will be a big help on the border.
