Evidently, American presidents wish to continue to guard Israel's nuclear "secret". If the motivation is thought to be a simple case of double standard, surely one must be deplored by the submissiveness of the general community. On the other hand, the more inquisitive mind would prod deeper and question the drive behind the guarding of this "secret"?
Perhaps motivations have changed over time. In 1969, Kissinger, aware that Israel had deceived the United States about its nuclear bomb program, which it was suspected to have stolen from the U.S., wrote to Nixon that pressuring Israel to reveal its nuclear arsenal would result in a Soviet nuclear guarantee for the [oil rich] Arabs and increase conflict in the region [i]. Ironically, it was Nixon who soon after had considered sending airborne troops to seize oilfields in Saudi Arabia, Kuwait and Abu Dhabi pursuing the 1973 war.
Today, the secrecy continues, as does the aid to Israel -- perhaps towards a messianic return - the building of the Third Temple.
In 2006, the Israeli government began work on an exact replica of the Hurva synagogue on its original site. The story of the Hurva has received little attention other than coinciding with Joe Biden's visit to Israel and that government's insistence on building more illegal settlements. But Hurva is the beginning of the end.
As the United States, acting as Israel's proxy, imposes its will on the world and pushes for sanctions and war on Iran, thereby distracting the international community, rabbis are being tailored for the special kind of garments they will be wearing in a "rebuilt temple". 'The Third Temple of the Third Jewish Commonwealth.' They believe that the return of Jews to Jerusalem are the obvious signs - "Less obvious are the more subtle realities that add up - the rebuilding of the Jewish Quarter, Jews steadily moving into the Old City, even the Temple Mount tunnel excavations. But alas, those big mosques are still situated on the Temple Mount. For now." [ii]
