Unlike the case of Iran today -- where a nation is publicly violating its NPT obligations and where the United States and the international community are acting in the open -- the White House in 1969 addressed the Israeli weapons program in a highly secretive fashion. That kind of deal-making would be impossible now.
Without open acknowledgment of Israel's nuclear status, such ideas as a nuclear-free Middle East, or even the inclusion of Israel in an updated NPT regime, cannot be discussed properly. It is time for a new deal to replace the Nixon-Meir understandings of 1969, with Israel telling the truth and finally normalizing its nuclear affairs.
