Our Afghan "ally"

The Afghan government was holding secret talks with the Taliban's No. 2 when he was captured in Pakistan, and the arrest infuriated President Hamid Karzai, according to one of Karzai's advisors.

The detention of Mullah Abdul Ghani Baradar -- second in the Taliban only to one-eyed Mullah Mohammed Omar -- has raised new questions about whether the U.S. is willing to back peace discussions with leaders who harbored the terrorists behind the Sept. 11, 2001 attacks.

Karzai "was very angry" when he heard that the Pakistanis had picked up Baradar with an assist from U.S. intelligence, the advisor said. Besides the ongoing talks, he said Baradar had "given a green light" to participating in a three-day peace jirga that Karzai is hosting next month.

Our troops are fighting and dieing to defeat the Taliban and secure Afghanistan's quasi-democratic government. If our capture of Taliban leaders makes the Afghan president "very angry", what and who are we fighting for?
