The Israelis have put up a security wall that stands about 30 feet tall. It has been very effective in stopping terrorist attacks. Think of what it could do for our illegal immigration problem!
I have to wonder how angry the POSOTUS, ICE, et al would get if there was a private fund raising drive (by FR?) to finance the building of the same kind of wall? And what if the Israelis were hired to build it? It would rankle Obama like you wouldn't believe. Have the Israeli company be the contractor who would hire local American skilled workers.
