That is the point that I was addressing and it is significant that neither of the critics commented on this beyond (in one case) suggesting that I hadn’t ‘proved’ my point. Readers may judge this latter assertion for themselves. It is clear from the insistence of the international community (as represented through the UN Security Council by the P5+1 group) that there is a case to answer, and the UN group are presently in Geneva putting it to Iranian representatives.
It is also noteworthy that Iran is a signatory to the 1968 Nuclear Non-Proliferation Treaty, through which it unequivocally committed itself (under Article II of the treaty), ‘not to manufacture, or otherwise acquire’ nuclear weapons. It thus cannot claim a ‘right’ to engage in such activities, whether or not there are other parties that have such weapons. By contrast, Israel, like India and Pakistan, did not sign the Treaty and is thus not in breach of it by the development of a nuclear arsenal.
