Not wishing to state the obvious Nickhere but in response to your:

"UN Resolution 487 passed on 19 June 1981 calls for Israel to put its atomic facilities under IAEA inspection and safeguards, and also for it to pay redress for its contemporary attack on Iraq's atomic facilities (Iraq, as a signatory to the NPT was entitled to pursue its atomic programme for peaceful purposes at that time)."

I do not believe that it is within the power or scope of the United Nations to force any country to sign a treaty against its will.

Israel's nuclear facilities are perfectly legal, their existance pre-dates any international nuclear agreement by ten years.

Anyone thinking that Iraq's nuclear programme was ever purely peaceful is living in cloud cuckoo-land, if anyone wishes to counter that I would advise them to look at the findings of the IAEA and the work they undertook in Iraq immediately after "Desert Storm". What was it again, pursuit of five independent means of enriching Uranium to weapons grade - Hmmmmmmmm - as Bobert would say.
