Karzai has already cast his lot with Pakistan

Subtitle of Guardian piece (via WPR Media Roundup) says it all:

Afghanistan's former head of intelligence says President Hamid Karzai is increasingly looking to Pakistan to end insurgency

Even with the evolution of our tactics, it's hard to blame Karzai for the choice. Obama gives him all indication of bailing before 2012, and the rushed effort in the south seems increasingly bogged down thanks to a very patient and brutal response from the Taliban.

There's been no effective regionalization of the solution set, leaving Pakistan the looming large neighbor of note, so what else do we expect of Karzai?

He's covering his bets.
