The latest edition of Survival: Global Politics and Strategy (published by the International Institute for Strategic Studies) hones in on two very different issues that have been giving policymakers sleepless nights recently: the eurozone crisis and the posssibility of a nuclear-armed .

In the free-to-view article 'Fiscal Union by Force', Alexander Nicoll argues that greater European fiscal union will be needed if the euro is to last (while Hanns Maull ponders ' Europe ’s Decline, Continued').

In 'Coping with a Nuclearising ' (also free), James Dobbins suggests how the West could respond if  Tehran acquires a nuclear weapon.

Also in this issue: succession politics in ; the economics of the Arab Spring; and how the war has strengthened NATO.
