In Collisions, Michael Kimmage, a historian and former State Department official who focused on the Russia-Ukraine conflict, offers a wide-angle, historically informed account of the origins of the current Russia-Ukraine war.

From the halls of power in Washington, Kyiv, and Moscow to the battlefields of Ukraine, Kimmage chronicles Putin's ascendancy to the Russian presidency, delves into multiple American presidencies and their dealings with Russia and Europe, and recounts Europe's efforts to bring Ukraine closer to the European Union. He tells the story of how Ukraine went from an embattled country on the edge of Europe to a formidable military power capable of pushing back the Russian military. Just as importantly, Kimmage captures how the current war has transformed multiple centers of power-from China to the United States-and dramatically altered the path of globalization itself. He makes the case that the war in Ukraine has shifted the direction of major macro-trends in world politics, contributing to the fragmentation of international politics, higher inflation, greater food insecurity, and the general collapse of arms control. These intersecting dangers amount to a new age of global instability, born in war and in the collision between Russia and the United States that has brought the world to the brink of a new Cold War.
