Peace to all. This is chicken & egg story. No end and no answer.

Whatever, I seriously think Middle east (including Israel) should be a nuke free region. Oil matters can explode easily. They must really think over and resolve differences by peaceful talks, not war or nukes.
Peace to the world.

If true, I believe Iran wants to develop nukes mainly b'cos of defence and as a deterrent. It probably don't need such weapons if US and Israel were not so threatening in the first place. To remove this mistrust, the 3 parties shld seriously consider meeting & negotiating for a nuke free middle east

This toing and froing did not occur when Israel developed Nuclear weapons or when it has fitted them to its submarine fleet. Maybe thats why the Iranians view this concern with contempt

Jim, Doncaster, Lincs

They should be negotiating the destruction of ALL nuclear related industries IMO...if there is a pole shift in 2012 or any other major tectonic movements ...which are inevitable... the whole world will have to pay for the nightmare created by the meltdown of a half dozen nukes or MORE...

moose, Roswell,

Which country on earth has ever used nuclear weapons killing hundreds of thousands of people in few hours in Hiroshima and Nagasaki? Does anyone know what is happening today to infants and children of Falluja, Iraq as a result of US phosphoric bombs used in 2004 and later? US can't say who should!

Given Iranian government's hardline nuclear policy, it is unlikely the new package will be accepted by Teheran, but the Europeans and the USA are proposing very good deal to Iran. Nuclear weapons in the hands of Islamic extremists is the most dangerous event and this can not be allowed.

David Dzidzikashvili, Cambridge, MA, USA

So how long is Iran supposed to get to consider this re-hashed proposal? And what really happens if they reject the deal? Business is business, and the Iranians will find some way to work around the sanctions; just look at the example of Cuba. So then, what happens?

The 6 world powers are asking the Iranian regime to stop enrichment or Iran as a nation without mullah's in the future ? The latter will be rejected by all Iranians. There is no logic in stopping what is legally Iran's right. If the west wants to negotiate, the door is open, but no preconditions.

Touran, London, UK

I love the way the headline characterizes this situation as Teheran's last chance on deal of nuclear power.
So then, what happens?
US/Israeli military action
This is precisely the same kind of rhetoric we saw leading up to the invasion and occupation of Iraq.

Mats, Stockholm,

The Iranians would be extremely foolish to give up enrichment, for that would subject their energy industry to the same sort of coercive extortion they are experiencing now.

A workable arrangement would perhaps to allow them enrichment with international inspectors and detailed monitoring.

Arik Silver, Milwaukee, USA

Given Iranian government's hardline nuclear policy, it is unlikely the new package will be accepted by Teheran. The 3 plus 3 should give much more serious thought on how to deal with a defiant Teheran in particular but with the clandestine proliferation of nuclear technology via Islamabad in general

Kailash N Pandit, New Delhi, India

To be just and even-handed, these six nations should also be considering the imposition of economic sanctions on Israel, which has developed its own nuclear arsenal in secrecy, and has never agreed to the Non-Proliferation Treaty.
