Before we go wasting billions of taxpayer dollars building this fence - which would be almost 2,000 miles long - why don't we go ask the Israelis how successful they've been in preventing smugglers from tunnelling under the steel and concrete barrier they built between Egypt and the Gaza Strip.



That's a pretty formidable wall there and it extends along the entire border between Egypt and the Gaza Strip - all 7 miles of it - and yet the Israelis (and the Egyptians up until Mubarak was deposed) could not stop smugglers from tunnelling under the wall.

If the Israelis cannot stop smugglers from tunnelling under a 7-mile wall that is as heavily fortified as that, then what on God's green Earth makes anyone but stark raving mad lunatic think that the US can stop smugglers from tunnelling under what would be a 2,000 mile wall, no matter how fortified?

If a totally perfect solution were needed you’d have a point. One that could cut the flow by an order of magnitude would be of great help.

Because jerk face the wall between the US and Mexico is about 90% un inhabited. The Gaza is densely populated. A lot of structures to hide tunnel efforts.

The wall separating Israel and the West Bank is a better example.

You guys are all talking about the wrong fence, think Korea.
