The Russians have more or less achieved what they had to on the ground. But the "donors" for the Republicans as well as the Democrats want to expand the war. Blinken and Nuland would like to fight the war to the last Ukrainian.
The interesting detail that should not be overlooked is this: even as Messrs McChrystal and Petreaus were talking “withdrawal” in 2011, Karzai had already contrived an extension until 2014. Karzai established his indispensability at a time when the Western media had written him off as “not even the mayor of Kabul” one “whose writ does not run beyond the Presidential palace”. If there was no consistent American stand on withdrawal from Afghanistan in 2010, why should we be convinced that the 2014 deadline is cast in stone?
