Nearly half of US diplomats, who do not want to serve in Iraq, say a key reason is because they do not support the Bush administration's policies there.
That is according to a survey carried out by the American Foreign Service Association, which represents the rank-and-file diplomatic corps, not political appointees.
The survey asked those who were not willing to go to Iraq why not, and those who were willing to go why.
State Department spokesman, Sean McCormack, said that people who signed up as foreign service officers were expected to support the policies of the US government.
"And if people have a problem with that, they know what they can do."
