I still think that it would be a wonderful symbolic move on Iraq's part to offer a battalion to fight in Afghanistan as part of an American brigade. But Iraq still helps us just by fighting jihadis on their own soil:
Iraqi authorities have obtained confessions from captured insurgents who claim al-Qaida is planning suicide attacks in the United States and Europe during the Christmas season, two senior officials said Wednesday.
A senior U.S. intelligence official confirmed the threat as credible.
Iraqi Interior Minister Jawad al-Bolani told The Associated Press that the botched bombing in central Stockholm last weekend was among the alleged plots the insurgents revealed. Iraqi Foreign Minister Hoshyar Zebari, in a telephone interview from New York, called the claims "a critical threat."
I expect Iraq to provide more and more help as time goes on, and for that help to eventually extend beyond today's battlefield in Iraq.
