Time was kind to the U.S. over its invasion of Iraq: the Bush Administration was able to waste four years pursuing misguided strategies there before finally getting things right last year and turning the situation around. But the new U.S. military approach to winning the war in Afghanistan is likely to take years, if not decades, to bear fruit, and there are growing signs that America's patience is fraying. On July 23, Vice President Joe Biden acknowledged that a lot more sacrifice would be required of Americans, but he insisted that it was worth the price to "straighten out" the Afghan-Pakistan border region because of the terrorism threat it potentially represents to Europe and the U.S. Still, American officials are lowering expectations after nearly eight years of fighting in Afghanistan, insisting that progress rather than victory is the best that can be achieved over the coming year.
