ARTICLE: "U.S. Erects Baghdad Wall To Keep Rival Sects Apart: 'They're trying to isolate us,' says one angry Sunni resident," by Edward Wong and David Cloud, New York Times, 21 April 2007, p. A6.

Echoing Friedman's point about the Palestinian-Israeli struggle playing Spanish Civil War to this Long War (sorry, Fox, you have to come up with a better title to replace the old one): suicide bombers shift to Iraq and now Afghanistan, so why not security walls?

Already the Sunnis are bringing up Native Americans ....

You can almost hear the rueful chuckling in Tel Aviv.

As I said in PNM, I don't mind walls per se, so long as you're trying to disconnect solely in terms of violence. But it's a tricky thing, and it speaks to somebody staying around for a very long time ...

But yeah, we know how to do walls. We've sat on some for decades to get what we wanted.
