Western military aid to Ukraine, economic pressure, and Russian battlefield losses could shift Kremlin leader Vladimir Putin’s perception of the war and potentially compel him to come to the negotiating table, - ISW “Any increased economic pressure against Russia — while a positive policy development — by itself is insufficient to force Russian President Vladimir Putin to the negotiating table or change Putin’s theory of victory. The continuation of Western military aid to Ukraine remains pivotal to the execution of a pressure campaign against Russia that could force Putin to recalculate his theory of victory,” the report reads.
