Iran isn't building nuclear weapons. They are building power stations. But Israel cannot accept this because Israel itself does indeed build nuclear weapons in a clandestine factory underneath the Dimona reactor complex. Rather than admit that Israel is the sole criminal in this regard, Israel tries to shed the guilt and stigma by constantly claiming that "everyone else does it."
This led to the bombing by Israel of the Osirik reactor in Iraq, again with the claim that Israel "just knew" that the Iraqis were building nuclear weapons in the power station. But following the invasion of Iraq, when UN experts examined the remains of the Orosik reactor, they found the remains of ... a power station. And nothing else.
Israel, as a nation, suffers from paranoid delusions about other nations that are a result of its attempts to transfer the guilt for what Israel does onto other parties. And people are dying as a result.
It is time to put Israel in a straight jacket before they harm themselves or anyone else.
