"Despite the US government’s silence on the issue, circumstantial evidence that Israel detonated a nuclear explosive device off the coast of South Africa on September 22, 1979, with the assistance of South Africa, keeps building. Such a test means that Israel and South Africa are in violation of the Limited Test Ban Treaty." "Continuing to hide Israel’s testing violation is a direct counter to the US claim that it stands for the rule of law and implies that the United States cannot be counted on to defend treaties if they are violated by Israel. This failure fosters cynicism about the seriousness of the United States and its allies on the restraining of nuclear weapons. In the wake of the Iran agreement, it underscores concerns that the United States has double standards on arms control when Israel is involved."
