Actually, I didn't get that sort of feeling from that letter.

If you read the letter, this guy seems pretty reasonable. Particularly when compared to other middle eastern leaders. But once again, our President is too much of a retarded cowboy to take it as an opening of communication, and chooses to ignore it.
Edit: When I say he is pretty reasonable, I dont mean compared to a reasonable person, I mean compared to Islamic extremists.
