In recent months, a growing number of voices – from political figures such as U.S. President Donald Trump and Slovak Prime Minister Robert Fico to various public opinion polls – have suggested that a resolution to the war in Ukraine may require Kyiv to cede some of its territory to Russia. These arguments, now gaining renewed attention as peace talks have begun, frame territorial concessions as a pragmatic step toward ending the conflict. Ceding Ukrainian land under these conditions, however, would reward historical revisionism as a geopolitical strategy and set a dangerous precedent in international law.
