4In this book, Magnus Nordenman explores the emerging competition between the United States and its NATO allies and the resurgent Russian navy in the North Atlantic. This maritime region played a key role in the two world wars and the Cold War, serving as the strategic link between the United States and Europe that enabled the flow of reinforcements and supplies to the European Allies. Nordenman shows that while a conflict in Europe has never been won in the North Atlantic, it surely could have been lost there.

With Vladimir Putin's Russia threatening the peace in Europe following the annexation of Crimea in 2014, the North Atlantic and other maritime domains around Europe are once again vitally important. But this battle will in many ways be different, Nordenman demonstrates, due to an overstretched U.S. Navy, the rise of disruptive technologies, a beleaguered NATO that woke up to the Russian challenge unprepared for high-end warfighting in the maritime domain, and a Russia commanding a smaller, but more sophisticated, navy equipped with long-range cruise missiles. Nordenman also provides a set of recommendations for what the United States and NATO must do now in order to secure the North Atlantic in this new age of great power competition.
