Scientific opinion now requires approval by the Bush administration.

The WHO is no longer allowed to talk directly to US scientific advisors. They must instead filter their request through a new office of the Bush administration, which ensures that they receive an "appropriate choice" for consultation. Scientific advisors are required to promote the administration's political agenda.

MSNBC - New limits placed on government scientists: Government scientists must now be cleared by a Bush political appointee before they can lend their expertise to the World Health Organization, a change that a Democratic lawmaker said fits a pattern of politicizing science. ...Steiger’s Office of Global Health Affairs now will choose “an appropriate expert who can best serve both of our organizations,” he said. HHS experts made available also must advocate U.S. government policies, Steiger said.

What conceivable reason does anyone have left to defend or support Bush? He is going to reduce the US to a third-world country if he keeps getting his way.
