But...I thought this wouldn't work!

Our politicians swore to us that building a fence along our border with Mexico would cost us billions, with no results!

I've never seen Israel do something designed to enhance their nation's security that didn't work. They're building a barrier along their southern border with Egypt. To prevent illegal immigration, and illegal workers from taking jobs and/or committing acts of terrorism.

Something tells me that it'll work for them. They have the testicular fortitude to enforce it.
