Robert Gates’ remarks ripped have the lid off a simmering disagreement between NATO allies and the US over Afghan strategy. The differences are not simply over troop levels and counterinsurgency competencies but at the level of basic national interest. For some NATO countries there is nothing in Afghanistan worth fighting at all for except the maintenance of good diplomatic relationships with America and the preservation of the Atlantic Alliance. But that will only go so far; and at any rate America can be counted on to carry the load alone because in contrast, the United States which directly suffered the September 11 attacks, sees a victory in the Afghan/Pakistani theater as a matter of vital interest. Therefore the US will carry on regardless. Even Hillary Clinton and Barack Obama periodically declare their commitment to winning in that theater. The US and the European NATO countries may differ even in their conception of victory. For the US, victory is defined as creating and maintaining friendly governments in both Kabul and Islamabad by defeating al-Qaeda and its allies. For the Europeans it may mean bringing the Taliban to power in exchange for giving up its support of al-Qaeda.
Which side of the debate is correct I leave the reader to decide. But so far as I can tell this is what the debate is about.
