Back in early 2007, when the Bush administration was insisting that its military intervention in a faraway land was not open-ended, Senator Barack Obama wasn't buying it.

So the freshman from Illinois used then-secretary of state Condoleeza Rice's appearance before the Senate Foreign Relations Committee as an opportunity to raise some probing questions about the exit strategy from Iraq. Senator Obama was particularly skeptical about the administration's alleged "benchmarks" for success. He wanted to know exactly what they were -- and what would happen if they weren't met. And he wanted to know the answer to this question: "At what point do we say: 'Enough'?"

Three and a half years later, that's an excellent question for President Obama, about Afghanistan. But he doesn't have an answer.
