Managed co-existence: What NATO could say about Russia

At last year’s Vilnius Summit, NATO pledged to develop a strategic approach to Russia. But with President Trump engaging Moscow directly and ending the “no business as usual” stance, consensus by the June summit in The Hague is unlikely. ELN Senior Associate Fellow and former UK Ambassador to NATO, Sir Adam Thomson, and Former NATO Assistant Secretary General for Operations, Stephen Evans, argue that in light of this, NATO should pursue a strategic shift—an internal deal towards a “managed co-existence” with Russia. This could align with Trump’s goals while preserving deterrence, sustaining European support for Ukraine, and keeping the U.S. committed to NATO.
