Enough to lie to them and slap them in the face. Twice just this week.
We take you back to July 20th...
Bush, July 20, 2007:
I’m joined by veterans and military families here to express support to our troops and their mission in Iraq. I want to thank you all for being here today. We’ve just finished a really good meeting. In our discussions, these folks had a message that all of us in Washington need to hear. It is time to rise above partisanship, stand behind our troops in the field, and give them everything they need to succeed. In February I submitted to Congress a Defense Department spending bill for the upcoming fiscal year that will provide funds to upgrade our equipment for our troops in Iraq and provides a pay raise for our military - a comprehensive spending request - that Congress has failed to act on.
Bush, May 16, 2007:
Military Pay: The Administration strongly opposes sections 601 and 606. The additional 0.5 percent increase above the President’s proposed 3.0 percent across-the-board pay increase is unnecessary.
That was Bush's "Statement of Administration Policy" on H.R. 1585, the "National Defense Authorization Act for Fiscal Year 2008," the bill that contained the authorization for that pay raise.
Bush, December 28, 2007:
I am withholding my approval of H.R. 1585, the "National Defense Authorization Act for Fiscal Year 2008," because it would imperil billions of dollars of Iraqi assets at a crucial juncture in that nation's reconstruction efforts and because it would undermine the foreign policy and commercial interests of the United States.
[...]
The adjournment of the Congress has prevented my return of H.R. 1585 within the meaning of Article I, section 7, clause 2 of the Constitution. Accordingly, my withholding of approval from the bill precludes its becoming law. The Pocket Veto Case, 279 U.S. 655 (1929). In addition to withholding my signature and thereby invoking my constitutional power to "pocket veto" bills during an adjournment of the Congress, I am also sending H.R. 1585 to the Clerk of the House of Representatives, along with this memorandum setting forth my objections, to avoid unnecessary litigation about the non-enactment of the bill that results from my withholding approval and to leave no doubt that the bill is being vetoed.
And why was he vetoing authority for a pay raise for the troops, again?
To block the enactment of a provision in the bill that allowed former American prisoners of war held by the Saddam Hussein regime to recover damages for the torture they say they endured while serving under arms for the United States.
Bush is vetoing the military pay raise in order to keep American POWs who were tortured from recovering for their injuries.
Forget for a moment that he's trampling on the Constitution to do it. Forget asking how much more of this the Congress can take.
How much more "support" like this can the troops take?
