Now, wait a second... when you take her quote out of context, it sounds terrible. But watching the video, she says something a little different than what is implied in Jay's link.
CURRY: [Do] you know the American people are suffering...watching this war...
BUSH: Oh, I know that very much, and believe me that no one suffers more than their president and I do, when we watch.
In context, the "suffering" they're discussing is NOT the individualized agony of losing loved ones, but a general attitude. In context, it's still hyperbole-- she's married to a politician, after all, what did you expect-- but it's hardly as insensitive as it's being made out to be.
