No, really, he is (hat tip to TPM):
The McCain administration would reserve all savings from victory in the Iraq and Afghanistan operations in the fight against Islamic extremists for reducing the deficit. Since all their costs were financed with deficit spending, all their savings must go to deficit reduction.
Upon further elaboration, the McCain camp added this:
It's pretty straightforward, as we win, costs will go down with a smaller footprint over time, and those savings will go to deficit reduction. It's really the logical extension of Senator McCain's position as articulated in the 2013 speech. Achieving success in Iraq would obviously lead to reduced expenditures on the effort.
Oh, right...this speech:
By January 2013, America has welcomed home most of the servicemen and women who have sacrificed terribly so that America might be secure in her freedom. The Iraq War has been won. Iraq is a functioning democracy, although still suffering from the lingering effects of decades of tyranny and centuries of sectarian tension. Violence still occurs, but it is spasmodic and much reduced. Civil war has been prevented; militias disbanded; the Iraqi Security Force is professional and competent; al Qaeda in Iraq has been defeated; and the Government of Iraq is capable of imposing its authority in every province of Iraq and defending the integrity of its borders. The United States maintains a military presence there, but a much smaller one, and it does not play a direct combat role.
Do you know what this reminds me of?
Yes, John McCain is trying to sell you underpants (for those who don't get the reference, please watch this).
