This week, for the second time since Russia’s full scale invasion of Ukraine, world leaders met to discuss the challenges facing the NATO security alliance.

With two previously isolationist nations, Finland and Sweden, newly joined or about to join - this week’s Summit in Vilnius, Lithuania spoke of a newly energised organisation.

But perhaps predictably in an age of war in Europe - there remain tensions and very big questions. The biggest of all - what to do about Ukraine?

To discuss what it means for the war in Ukraine; the nature of global security, and the still-dominant role the USA plays in this post-WW2 organisation, Arthur Snell is joined by:

 - Dr Ulrike Franke: senior fellow at the European Council on foreign relations

 - John Lough: Chatham House associate fellow of the Russia & Eurasia Programme and the former NATO man in Moscow

 - Steven Pifer: former US ambassador to Ukraine and senior fellow at The Brookings Institution.
