She said the Wounded troops she just visited helped her make up her mind. mmmmmm would like to have been a fly on the wall.
I would guess that two things happened. 1) She saw the wounds that the soldiers received in service to their country, swapped stories about the wounds that she and her family have received so far, and then listened to them telling her that they have not given up, and that she shouldn't either, and 2) Probably received some advice from the special ops guys, something to the effect of: Don't just stand there for the next 18 months like a dumb moose waiting to get shot at.
