On [May 16], the Senate Armed Services Committee held a hearing on whether the statutory basis for [the Global War on Terror"] - the 2001 Authorization to Use Military Force (AUMF) - should be revised (meaning: expanded). Asked at a Senate hearing today how long the war on terrorism will last, Michael Sheehan, the assistant secretary of defense for special operations and low-intensity conflict, answered, 'At least 10 to 20 years.' The military historian Andrew Bacevich has spent years warning that US policy planners have adopted an explicit doctrine of "endless war". Obama officials, despite repeatedly boasting that they have delivered permanently crippling blows to al-Qaida, are now, as clearly as the English language permits, openly declaring this to be so. It is hard to resist the conclusion that this war has no purpose other than its own eternal perpetuation. This war is not a means to any end but rather is the end in itself. The "war on terror" cannot and will not end on its own [because] the nation's most powerful political and economic factions reap a bonanza of benefits from its continuation. The genius of America's endless war machine is that, learning from the unpleasantness of the Vietnam war protests, it has rendered the costs of war largely invisible.
