Since spring 2014, Russian President Vladimir Putin has been waging a hybrid war against Ukraine to prevent the country’s departure from the Kremlin orbit. This unconventional campaign involves military, economic, diplomatic, and informational components. Underpinning it all are Russia’s historic claims to much of present-day Ukraine. Putin makes little effort to disguise his contempt for Ukrainian statehood. Instead, he argues that Ukraine has always been part of Russia’s traditional heartlands and is destined to remain so, whether Ukrainians like it or not.
