Executive Summary
On February 24, 2022, Russia’s unprovoked invasion of Ukraine presented the world with a dramatic challenge to the rules-based international order. Ukraine’s fierce and continuing resistance has earned the backing of Western democracies. Under the leadership of the United States, democracies in Europe and the Indo-Pacific have rallied to provide political, diplomatic, and military support to Ukraine. As of this writing, despite difficult coordination on sensitive military issues, that unity remains intact.
In the Indo-Pacific, Russia’s invasion of Ukraine brought preexisting security challenges into sharper relief. Across the region, security concerns were heightened and acquired greater definition in the Taiwan Strait and on the Korean Peninsula. More broadly, Russia’s aggression called into question the staying power of the rules-based international order and, at the same time, raised recognition of the inseparable nature of that order. As the United Kingdom’s former Foreign Secretary Liz Truss told the Atlantic Council on March 10, “conflict anywhere threatens security everywhere. Euro-Atlantic and Indo-Pacific security are indivisible.”1
This study begins with a consideration of the Indo-Pacific security environment as it evolved during 2022. It goes on to consider the measures by key regional actors—primarily but not exclusively the United States, Japan, the Republic of Korea, Australia, and India—that strengthened deterrence in the face of an increasingly challenging environment. Expanding diplomatic coordination and security cooperation reflects a strategic commitment by the region’s democracies to support a rules-based order and advance a shared vision of a free and open Indo-Pacific. At the same time, European democracies have continued to expand diplomatic and security engagement with Indo-Pacific partners.
The policy challenge for the United States and Western democracies has been to resist Russia’s aggression in Europe in support of the rules-based international order and, at the same time in the Indo-Pacific, to strengthen deterrence against the use of force or coercion to change the status quo.
