Survival, the IISS's bimonthly journal, challenges conventional wisdom and brings fresh, often controversial, perspectives on strategic issues of the moment.

In this issue:

Francois Heisbourg assesses that Ukraine might have to accept the de facto division of the country to secure a fast track into NATO Daniel Byman writes that state ties to terrorist groups are likely to feature in the western alliance's long-term confrontation with Russia and in its rivalry with China Juan Pablo Medina Bickel and Irene Mia assess that global climate mitigation and the energy transition could reinforce South America's geopolitical clout

From the Survival archives, the late David P. Calleo predicted in 1999 that a successful euro would enhance the EU's diplomatic and military capabilities, while the late James Dobbins considered in 2012 how the US could prevent a war with China

Dana H. Allin and John L. Harper reflect on long-time Survival contributing editor David P. Calleo's legacy

And nine more thought-provoking pieces, as well as our regular Book Reviews and Noteworthy column.
