In the weeks that followed, clear evidence for a nuclear test emerged from hydrophones near Ascension Island and a jump in radioactive iodine-131 in Australian sheep. Only nuclear explosions produce iodine-131.
But the test came at a bad time for US President Jimmy Carter, who was gearing up his re-election campaign, a cornerstone of which was a peace agreement between Israel and Egypt.
If the Israelis were seen to have violated the Partial Test Ban, as well as the 1977 Glenn Amendment to the Arms Export Control Act, the US would have been required to cut off all arms sales to Israel and apply heavy sanctions. Carter was nervous about what such a finding would have on the election, since a major part of Carter's platform was arms control and non-proliferation.
So Carter threw together a panel of experts whose job was not to examine the incident but to cover it up. The Ruin -- a Panel cooked up a tortured explanation involving mini-meteors that the media accepted and, as a result, so did the American public.
But nuclear physicists knew the panel was blowing smoke and that the evidence was unarguable. The device was set off on a barge between Prince Edward Island and Marion Island (the former should not be confused with Canada's Prince Edward Island) with a yield of from 3 to 4 kilotons. A secret CIA panel concurred but put the yield at 1.5 to 2 kilotons. For comparison, the Hiroshima bomb was 15 kilotons.
It was also clear why the Israelis took the risk. Israel had a number of Hiroshima-style fission bombs but was working on producing a thermonuclear weapon -- a hydrogen bomb. Fission bombs are easy to use, but fusion weapons are tricky and require a test. That the Vela picked it up was pure chance, since the satellite had been retired. But its bhangmeters were still working.
From Carter on, every US president has covered up the Israeli violation of the 1963 Partial Test Ban Treaty, as well as the 1968 Nuclear Non-Proliferation Treaty (NPT). So when Netanyahu says Iran is lying about its nuclear program, much of the rest of the world, including the US nuclear establishment, rolls their eyes.
As for Turkish President Erdogan, he is perfectly correct that the nuclear powers have broken the promise they made back in 1968 when the signed the NPT. Article VI of that agreement calls for an end to the nuclear arms race and the abolition of nuclear weapons. Indeed, in many ways Article VI is the heart of the NPT. Non-nuclear armed countries signed the agreement, only to find themselves locked into a system of "nuclear apartheid," where they agreed not to acquire such weapons of mass destruction, while China, Russia, Great Britain, France and the US get to keep theirs.
The "Big Five" not only kept their weapons, they are all in the process of upgrading and expanding them. The US is also shedding other agreements, like the Anti-Ballistic Missile Treaty and the Intermediate-Range Nuclear Force Agreement. Washington is also getting ready to abandon the START treaty that limits the US and Russia to a set number of warheads and long-range strategic launchers.
