My man. There are international treaties on nuclear weapons. Everyone knows the Israel's tricks.
What treaty are you talking about?
The NPT - which Iran is a signatory of but Israel is not - is the foremost treaty in the nuclear field and governs the rights of signatories.
"Article IV
1. Nothing in this Treaty shall be interpreted as affecting
the inalienable right of all the Parties to the Treaty to develop research, production and use of nuclear energy for peaceful purposes without discrimination and in conformity with Articles I and II of this Treaty.
2. All the Parties to the Treaty undertake to facilitate, and have
the right to participate in, the fullest possible exchange of equipment, materials and scientific and technological information for the peaceful uses of nuclear energy. Parties to the Treaty in a position to do so shall also co-operate in contributing alone or together with other States or international organizations to the further development of the applications of nuclear energy for peaceful purposes, especially in the territories of non-nuclear-weapon States Party to the Treaty, with due consideration for the needs of the developing areas of the world."
