In this week's issue of the New Statesman, we look at why Barack Obama's attempts to bring Iran in from the cold have failed. The country's atomic ambassador to the IAEA tells David Patrikarakos that Iran will never give up enrichment, whatever the consequences.
Elsewhere, our political correspondent, James Macintyre, has an exclusive interview with Martin McGuinness, Northern Ireland's deputy first minister. McGuinness speaks openly about death threats, his "amazing" friendship with Ian Paisley, and whether Sinn Fein could work with a Tory government.
In the columns, Mehdi Hasan dispels the myth of the "ticking bomb"; David Blanchflower accuses the 20 economists who wrote to the Sunday Times of political opportunism; and Andrew Stephen looks at what's next for Hillary Clinton.
In The Critics, Geoffrey Wheatcroft is impressed by a new biography of Arthur Koestler; Jude Rogers explains why Joanna Newsom is a Joni Mitchell for the 21st century; and Will Self turns his eye to conspiracy theories.
