If you have a functioning illegal community for the aliens to enter, you will have an inflow of illegals. By changing tactics on border control you can produce short term impact, but over the long haul, the motivated will find a way in because if they get in they can melt into the functioning illegal community. The bottom line is that deporting 1 to 2 million per year will not diminish the size of the illegal population within the country.
I just don't think you're right. But, at this point neither of us can prove our point (or can you?).
