Most experts agree that the Russia-Ukraine war will have to come to an end at some point. And policy makers agonize over how to ensure a peace that is both permanent and meaningful. Lasha Tchantouridzé argues that the West needs to go further than simply supplying arms and ensuring NATO membership to bring a long-lasting ceasefire. 

Although Moscow has given occasional assurances to the contrary, it is widely accepted that the Russo-Ukraine war will eventually come to an end. However, it is also anticipated that Moscow may resume its campaign in Ukraine after a period of relative peace. Given this, it is in the interest of Kyiv and its supporters to seek a lasting peace settlement that would enable Ukraine to defend itself in the future. This will require catching and holding Moscow's undivided attention by targeting and threatening at least one major strategic asset of the Russian Federation, which is the Black Sea Fleet with its home base in Sevastopol. If Russia were to lose its Black Sea navy, its fight for Sevastopol and Crimea would lose strategic significance, and Moscow would be more willing to negotiate a compromise settlement in Ukraine.

To achieve this goal, Kyiv must acquire the necessary weapons systems to bring Russia to the negotiating table. Moscow is likely to accept one of two possible peace settlement scenarios, provided that each allows for ample room for compromise. The first scenario involves restoring the status quo ante bellum and allowing Ukraine to join NATO. The country would remain divided for the time being, with the Cold War division line drawn in the Donetsk suburbs. This scenario is similar to the settlement imposed upon Germany after World War II, which eventually led to reunification.
