Read about this letter from Al Zawahiri to Al Zarqawi:

Zawahiri also complains about Zarqawi’s all-out war against the Shiites of Iraq, saying the Arab man in the street doesn’t understand why suicide bombings are killing so many fellow Muslims.

The letter also indicates Zawahiri’s life in hiding has left him cut off from news and financial support. He asks Zarqawi to provide him more information about operations in Iraq, saying he should know at least as much as the enemy knows, and he even asks Zarqawi to send money.

Well, maybe Zarqawi is losing Zawahiri’s support, but he’s still got Michael Moore and Ted Kennedy in his camp…

I have to say, though, I don’t know what it is that CBS finds “chilling” about the letter.

Then read this (long but worthwhile) report from Mosul by Michael Yon, if you want to know who’s winning, and who’s losing, this war.
