Does the US want Britain to renew its independent nuclear deterrent? The question is generating a certain amount of debate among security analysts on both sides of the Atlantic. Between now and 2016, the UK must take a decision on whether to spend £20bn building four new submarines to carry the Trident missile. David Cameron’s Conservatives are keenly committed to a like-for-like replacement, saying there can be no compromise with the UK’s ultimate security guarantee.

But there are a few discordant voices out there who are questioning whether it is really worth ploughing all this money into a renewed nuclear weapons capability when the UK is having to cut its conventional arsenal as much as it is. Would it not be better, ask some critics, if Britain shifted the billions of pounds of cash meant for Trident’s replacement and bought weapons it is far more likely to use and which will ensure it remains an effective ally of the US? Read more

As Barack Obama visits Israel and the Palestinian Territories this week, he will doubtless find that one issue tops all others for the Israeli government: the need to persuade him to make a firm commitment to take military action over Iran’s nuclear programme if negotiations to scale back Iranian ambitions eventually break down.

President Obama said recently that he does not think Iran will be in position to get a nuclear weapon for at least another year. But Benjamin Netanyahu, Israel’s PM, is still looking for a firmer commitment from the White House that if the Iranians take their nuclear capability beyond a certain point, the US will take military action.

Whether differences between the US and Israel will be closed on this trip – or at some other point – is far from clear. Although it says Iran must not get a nuclear weapon, the US administration certainly views the timeframe for the Iranian programme in a more relaxed way than the Israelis do. Read more

The latest meeting between Iran and world powers to try and resolve the dilemma over the Iranian nuclear programme is over. And once again, a shaft of light has emerged that will lead some to hope that military action over the Iranian programme might be averted.

After two days of talks in the freezing city of Almaty in Kazakhstan, Iran has told the US and five other world powers that it is prepared to hold a couple more meetings in March and April to try to resolve international concerns that it wants a nuclear bomb.

That said, few will want to overplay the significance of this move. Here are three reasons why many western diplomats will be cautious. Read more

Can Barack Obama use his second term of office to push through another round of cuts in American and Russian nuclear weapons? After declaring in his State of the Union address that he will “engage Russia” on this issue, the question is suddenly back on the international security agenda.

In his first presidential term, President Obama and his then Russian counterpart Dmitry Medvedev pushed through big cuts in the number of deployed nuclear weapons each side possesses, with each pledging to have no more than 1,550 each by 2018. Now, Mr Obama has come back to the issue and says he wants to do more – with his officials indicating they want to see deployed US and Russian nuclear weapons coming down another third – to around 1,000 on either side.

Discussions about US- Russia arms control are very technical and the detail quickly gets mind-boggling. To the outsider, the subject also seems dispiriting. Even a big cut like the one Mr Obama is proposing would still leave both countries with massive capability to destroy each other and the world. Still, there are a number of reasons why Mr Obama’s attempt to get new cuts is worth attention in the months ahead. Read more

In February, the weather in Almaty is usually well below freezing. So as some of the world’s top diplomats prepare to travel to the former capital of Kazakhstan this month for yet another meeting with Iran over its nuclear programme, most will be feeling somewhat gloomy. The concern is not just the weather, of course, The thing that will induce angst is the near-certain prediction that they will sit there for days in the freezing cold of the southern Kazakh mountains – only to make no progress yet again in talks with Iran over its nuclear ambitions. As one top diplomat tells me: “The best I’m hoping for is that we agree another date to meet. That’s it.”

Judging by the advanced briefing for this meeting – where Iran will negotiate with the US, Britain, France, Russia, China and Germany – it’s easy to see why Almaty is set to join Istanbul, Baghdad and Moscow as the scene of another negotiating failure. Read more
