Here are a couple of articles relating to the last post:
- "Leading Senator Calls for Change in Self-Defeating US Policy on UNESCO", UN Dispatch, February 8, 2013
- "Obama’s budget’s surprise: Restore UNESCO funding!" The Washington Post, 02/16/2012
In terms of foreign policy, I agree with Senator Leahy that U.S. funding for UNESCO enables it to do more to achieve our objectives than would an alternative use of the funds. I don't think that restoration of funding to UNESCO would significantly damage our relations with Israel, and it might help a little with opinion about the USA in the Arab and Islamic worlds.
In terms of domestic policy, the lobby that pushed through the 1990 legislation still exists and will probably oppose any change in that legislation.
