Project 1721: A U.S. Army War College Assessment on Russian Strategy in Eastern Europe and Recommendations on How to Leverage Landpower to Maintain the Peace [open pdf - 5MB]
"In early 2015, the U.S. Army War College (USAWC), at the request of the former Army Chief of Staff, General Raymond Odierno, published 'Project 1704', a study that discussed the changing strategic environment in Europe spawned by Russian aggression against Ukraine. The chief questions addressed by 'Project 1704' included: (1) What is the Russian strategy in the region? (2) What is the appropriate North Atlantic Treaty Organization (NATO) and U.S. response? (3) What are the implications for NATO and U.S. Landpower? [...] 'Project 1721' takes up where 'Project 1704' left off. The geo-strategic situation continues to change. Although many trends are disconcerting, there are points of light in the darkness. Chief among these is that Putin's aggressive tone and approach is forging a greater unity among NATO members hitherto not seen since the 1980s. [...] The increasingly bombastic rhetoric and actions of the Kremlin is disconcerting and is placing European peace in a precarious situation-where one misstep by Moscow or Washington, D.C. could plunge the world into a costly war. Yet, weakness and lack of resolve from 'the West' is not the answer. The world experimented with appeasement when faced with another nationalistic leader in the form of Adolf Hitler. The cost of capitulation and appeasement was a costly world war."
