That was a real "oops!", it seems

Israeli Prime Minister Olmert's apparently slip about his country's nuclear arsenal, that is.

Gulf states call for sanctions on Israel for having nuclear weapons by Yossi Verter Ha'aretz 12/13/06:

Following Prime Minister Ehud Olmert's apparent public confirmation that Israel possesses nuclear weapons on Monday, an organization representing six Persian Gulf states called on the United States and the international community to "place sanctions on Israel for their nuclear program."

Gulf Cooperation Council Secretary-General Abdul Rahman ibn Hamad al-Attiyah, said Tuesday "the U.S. must not apply double standards since it calls for sanctions on countries that have nuclear programs that we have not ruled out are framework of nuclear weapons." According to al-Attiyah, the world must regard Olmert's statement as a global threat to peace and security.

A big part of the diplomacy behind Israel not admitting to its nuclear weapons was that doing so would trigger formal demands for sanctions.
