Charles Krauthammer wonders why we can’t build the fence first:
A barrier is a very simple thing to do. The technology is well tested. The Chinese had success with it, as did Hadrian. In our time, the barrier Israel has built has been so effective in keeping out intruders that suicide attacks are down more than 90 percent.
Comprehensive immigration reform has simply too many contentious provisions to command a majority of Congress or the country. We all agree on enforcement, don’t we? So let’s do it. Make it simple. And do it now. Once our borders come visibly under control, everything else will become doable. Including amnesty.
Actually building the fence, rather than just throwing more money in the pot would surely pave the way for a comprehensive immigration program that "people of good will" can support, isolating the nativists on the one side and the open borders transnationalists on the other.
