Be in no doubt about the stakes: the defensive system that Mr Obama has chosen to scrap was the West's ultimate insurance policy against a nuclear-armed Iran. If all our efforts to prevent Tehran from acquiring a nuclear arsenal were to fail, this anti-missile shield would have provided a measure of assurance.
Mr Obama's decision to gamble with Europe's security – for this is what it means – can only be defended if he now secures a real and incontestable gain. That hinges on Russia. The Kremlin, which bitterly opposed the missile-defence scheme, has had its way. In the next few weeks, we will all learn the answer to the burning question: what will Russia give in return? There is no doubt about what Mr Obama wants. Iran's nuclear programme continues apace and the underground centrifuges in Natanz are still enriching uranium in brazen defiance of five United Nations resolutions. Only yesterday, President Mahmoud Ahmadinejad said his country would "never" halt this highly sensitive process, which could be used to produce nuclear weapons.
We are nearing the endgame of diplomacy towards Iran. On October 1, Tehran's chief negotiator will meet an American official at a gathering of the world's leading powers. If those negotiations fail – and no one is predicting success – Mr Obama will place a new sanctions resolution before the Security Council. This time, America will probably seek to target Iran's oil and gas industries, perhaps by imposing a UN ban on any investment in this vital sector.
Will Russia allow such a resolution to pass – or will Moscow follow its usual practice and ally with China to shield Iran? If the Kremlin vetoes or dilutes a sanctions resolution, this will make a peaceful resolution of the confrontation with Iran far less likely, and shorten the odds on a war in the Middle East next year. It will also show that Mr Obama's monumental gamble has failed. The President has effectively placed the fate of a vital element of his foreign policy in the hands of the Kremlin. That is a sorry pass for a superpower to reach.

This is the second thing that is bothering me. Frankly I don't want this man's incompetence to hurt this Country and I don't want Hillary harmed by his poison. Governor Clinton may be her best bet.
