In the summer of 2014, Russia forcibly annexed Crimea from Ukraine and then actively supported ethnic Russian separatists in an on-going irredentist bid in Eastern Ukraine. This aggressive policy threatens to challenge NATO and the United States in its support of Ukraine and other nations of Eastern Europe. From this changing strategic environment, three central questions emerge: (1) What is the Russian strategy in their periphery? (2) What is the appropriate U.S. response? (3) What are the implications for U.S. landpower? Vladimir Putin's grand strategy relies on a complex mix of diplomatic, informational, military, and economic factors to preserve and expand Russian global power. Putin's strategy hinges on maintaining internal legitimacy, advancing a narrative of Russian greatness, manipulating nationalism, and protecting sources of revenue. He seizes opportunities to improve his position by controlling the media and the wealth of the elite class.
