Also saying "The war on terror" is kind of misleading since troop levels have varied greatly. To give one example the initial Afghan offensive only involved about 1,300 ground troops. As of 2003 that number was still only at 10,000 (http://www.cbsnews.com/stories/2009/12/01/ap/government/main...)
That's around the same number we had in Somalia (5,300), the '89 Panama invasion (30,000) and several other conflicts. So the fact that the chart starts to level off as of 2001 while these other conflicts don't seem to have made an impact undermines the implied point
