Nuclear Iran - Shirley Williams and Geoffrey Robertson

On Start the Week Andrew Marr discusses the prospect of an Iran with nuclear weapons. David Patrikarakos points to the failure to understand how far Iran's nuclear strategy is linked to its recent history and sense of identity. Geoffrey Robertson QC argues that the production of atomic bombs should be made an international crime against humanity, whereas Baroness Shirley Williams believes that politics still has a role to play in disarmament around the world. But Douglas Murray dismisses the idea that political negotiation or the law will work, and believes force may be the only answer.
