And here we have your proof - it's SPECULATION.
The CBO estimates assume that 75,000 troops will remain in both countries through 2017, including roughly 50,000 in Iraq. That is a "very speculative" projection, though it's not entirely unreasonable, said Loren Thompson, a defense analyst at the non-partisan Lexington Institute.
As of Sept. 30, the two wars have cost $604 billion, the CBO says. Adjusted for inflation, that is higher than the costs of the Korea and Vietnam conflicts, according to the Washington-based Center for Strategic and Budgetary Assessments.
The figures in the graph in the OP are as of 2010. Please learn to read for comprehension.
ahh yes the same specualtion used in the projected Obama defecit charts that are so popular among the right.
Can you tell the difference between 2010 and 2017?
sure but can you?
