How many Arab terrorists are getting through the Israeli fence?

The answer, of course, is almost none.

We don't lack the ability to completely secure our border. All we lack is the political will.

The fence image you posted is between Israel and the Egyptian Sinai and is one of the places where they recently found hundreds of sophisticated tunnels under the wall. So your claim of almost no terrorists getting through is demonstrably false.

Palestinians also regularly use ladders to go over or sledgehammers and blowtorches to go through holes in the West Bank wall.
