As I understand it, an exit strategy is a sort of poor man's Powell Doctrine. It does not demand certain and prompt victory. It merely demands a certain and prompt conclusion to the exercise that is acceptable to the United States. So you're golden. Tim, I support the president.
American credibility is at stake.
The commander in chief has made a commitment on behalf of the United States, and the United States must honor that commitment. You get to be patriotic and hawkish. And if things go well, you were behind the commander in chief all the way. But if things go badly, it is the president's fault for making the commitment. Tragically, you had no choice but to support him once the commitment was made, but of course making it was irresponsible folly.
