Obama, the US president, has agreed to abide by a 40-year policy of
allowing Israel to keep nuclear weapons without opening them to
international inspection, according to a US newspaper.
In a report on Saturday, The Washington Times quoted three
unnamed sources as saying Obama had confirmed to Binyamin Netanyahu,
Israel's prime minister, that he would maintain the "don't ask, don't
The incident reportedly occurred when the two met at the White House in Washington DC in May.
Neither Israel's embassy in Washington, nor the White House National Security Council would comment on the claim.
Cohen, an Israeli expert and author, was quoted by the paper as saying
that under the deal "the United States passively [accepts] Israel's
nuclear weapons status as long as Israel does not unveil publicly its
capability or test a weapon".
There is no official accounting of the deal, supposedly agreed in
1969 between Richard Nixon, then US president, and Golda Meir, the
Israeli prime minister at the time.
In an interview last week with Israel's Channel 2 media company,
Netanyahu spoke of his confidence that Obama's recent remarks on a
world free of nuclear weapons would not apply to Israel.
"It was utterly clear from the context of the speech that he was speaking about North Korea and Iran," the Israeli leader said.
"But I want to remind you that in my first meeting with President
Obama in Washington I received from him ... an itemised list of the
strategic understandings that have existed for many years between
Israel and the United States on that issue.
"It was not for naught that I requested, and it was not for naught that I received [that document]."
Although there is no formal record of the understanding - nor have
Israeli nor American governments ever publicly acknowledged it - some
documents hint at an agreement between the two nations.
In 2007, the Nixon library declassified a July 19, 1969, memo from
Henry Kissinger, then national security adviser, that comes closest to
articulating US policy on the issue.
That memo says "while we might ideally like to halt actual Israeli
possession, what we really want at a minimum may be just to keep
Israeli possession from becoming an established international fact".
