The United States pulled out of UNESCO under President Ronald Reagan, rejoining two decades later under President George W. Bush.
So does that mean that Bush Jr gets a -100?
Ah well, it's their own money and they can darn well do with it what they please. (maybe with this reduction in funds the UN won't be able to roam the US country-side in black SUVs and choppers anymore!)
Smart move by Obama, there's an election next year and he can't risk coming off as pro-science.
