Not surprising really, when you think about it. Since Obama stated to the world that the U.S. has no intention of beating the Taliban and will begin retreating 18 months after staging a surge, Karzai is looking down the road to his new stark reality.
White House spokesperson Gibbs and other had defended the disastrous speech at West Point by saying that the 18 month withdrawal time-line was just 'a goal', and that conditions on the ground would dictate what really happens, and that the 18 month time-line was intended to tell the Afghan government that we would not be there forever so they better get on top of defending themselves.
Karzai has clearly received the message. He and the Taliban now realize that Obama is pulling out and it is not even a matter of time. We all now know the time-line.
