That's good news. I also read a report that Zarqawi has gotten crosswise with some of the western Sunni tribes.
Oh yeah, the tribes are slaughtering the foreign terrorists as they cross the border. Those tribes have been running a lucrative smuggling business for centuries and they're really not happy that the foreigners have brought the Americans to their neck of the woods. In addition, the stupid terrorists have been intimadating the villagers not realizing that the tribes have a responsibility to defend them as they are tribe members.
There are other tribes who see the potential for lots of money if the Iraqi government is a success, so they're joining in as well.
