jeez, looks like the Israelis even built a moat! What's that for burning oil? ;^D
On a serious note, the security wall in Israel has cut the homicide bombing attacks way down.
I'd bet our illegal problem would drop down to almost nothing, if we spent the money on a wall, instead of chasing them through the desert.
But no, we can't have that!
Yes it has.
I noticed the moat, too. Flaming oil ! LOL !
