Some mother, Mrs. Churo, told Romney that her daughter, serving in Afghanistan, wants to know why we are still there after having killed Bin Laden. The mother says the daughter is confused about why she is still there. I take it that the daughter thought the mission in Afganistan had been to take out Bin Laden which was not the case, and that when we did take him out and didn't leave, it dawned on her that the mission was a different one, but in the ensuing year she hadn't been able to ferret out what that mission was. Apparently, now she has given up trying. Quoting the mother quoting the daughter "There is no mission here. We have no definition of a mission."
Romney took a dim view of this. "If your daughter is not familiar with the mission that she's on, how in the world can the commander in chief sleep at night, knowing that we have soldiers in harm's way that don't know exactly, precisely, what it is that they're doing there". Actually, it was soldier, not soldiers, but he's proabably right, there's more than one. But here's the kicker. Romney knows what the mission is. Romney said, he fully understood its purpose to be helping Afghan forces to achieve sovereignty and security."
The way I see it, the President must have called Romney and told him what the mission was adding "but don't tell Churo." Then tried to get some sleep. Most likely it didn't sit well with Romney that he was keeping this information under his hat and couldn't sleep himself. That's why he figured the President couldn't sleep either. So it was a bleary-eyed Romney that slipped up and told the mother what the mission is. Hopefully, the mother will now tell her daughter and everybody can get some sleep.
