Why is Crimea critical to the Russia–Ukraine war?

Ukraine's recent intensified attacks on Russian-controlled Crimea highlight the strategic importance of the region in the ongoing conflict. Crimea's control has long been a flashpoint, representing a significant territorial gain for Russia after its annexation in 2014. As Kyiv ramps up pressure on Crimea, it's not just about reclaiming land but also about undermining Moscow's military and political leverage. This move could reshape the dynamics of the war, potentially shifting the balance of power and affecting global geopolitical relations.
