“Because I told them it had to."

From Think Progress:

“He’s tried this two times — it’s failed twice,” House Speaker Nancy Pelosi (D-CA) says of President Bush’s escalation plan.

“I asked him at the White House, ‘Mr. President, why do you think this time it’s going to work?’

And he said, ‘Because I told them it had to.‘”

Pelosi reportedly then asked, “Why didn’t you tell them that the other two times?“
