"WASHINGTON - A prominent right-wing political pundit has called for the United States to withdraw its troops from Afghanistan, the latest sign of a growing disenchantment in the US with the war.
Hawkish commentators have already assailed Washington Post columnist George F Will for his Tuesday column, entitled "Time to Get Out of Afghanistan"......
Top US officials have called on skeptics to give McChrystal 12 to 18 months to implement his new strategy and demonstrate progress.
But as the controversy over Will's column indicates, there appears to be little patience in the US for a costly and extended war effort. In Washington, the political clock is ticking."
