The BBC has an article with some good points on why Bush is likely to ignore the letter:
The influence of the current State Department on the Bush administration is debatable. The influence of former diplomats is minimal.
And the writers of the letter have a problem in that several of them are connected to a lobby group active in Middle East affairs, often as a voice
for the Palestinians.
Another problem is that there are so far few big names on the list of signatures. Washington is a city which likes big names.
Hopefully the public impact of the letter won't be as minimal.
