Douglas Birch and R. Jeffrey Smith write: Israel has a substantial arsenal of nuclear weapons.

Former CIA Director Robert Gates said so during his 2006 Senate confirmation hearings for secretary of defense, when he noted—while serving as a university president—that Iran is surrounded by “powers with nuclear weapons,” including “the Israelis to the west.” Former President Jimmy Carter said so in 2008 and again this year, in interviews and speeches in which he pegged the number of Israel’s nuclear warheads at 150 to around 300.

Its consequence has been to help Israel maintain a distinctive military posture in the Middle East while avoiding the scrutiny—and occasional disapprobation—applied to the world’s eight acknowledged nuclear powers.

But the U.S. policy of shielding the Israeli program has recently provoked new controversy, partly because of allegations that it played a role in the censure of a well-known national-laboratory arms researcher in July, after he published an article in which he acknowledged that Israel has nuclear arms. Some scholars and experts are also complaining that the government’s lack of candor is complicating its high-profile campaign to block the development of nuclear arms in Iran, as well as U.S.-led planning for a potential treaty prohibiting nuclear arms anywhere in the region.
