No sooner had Tony Blair announced a withdrawal of some British troops from Iraq, then it emerged that more soldiers will be going to Afghanistan. This is not so much a scaling back of Britain’s military commitments overseas, as a re-deployment from one battlefront to another.
There is an unstated logic behind the British move. Iraq is going very badly – and the war may eventually be lost. Under these circumstances, it becomes all the more crucial that the western allies prevail in Afghanistan. Two defeats in the "war on terror" (or whatever you want to call it) would be catastrophic.
