Much of the world is focused on the war in Ukraine, the destruction that Russia’s attack is causing, and Ukraine’s stalwart defence. The sanctions levied on Russia are a potent reminder of the strength of the transatlantic relationship. Yet for the U.S. as a global superpower, competition and cooperation with China and U.S. commitments to defend allies and buttress Taiwan’s defence remain core security policy interests. How will the United States navigate this perilous moment in global security, and how should its military be shaped to contribute to the national strategic goals? Elbridge Colby’s answer to the question, ‘what is the best defense strategy for America?’ will provide much food for thought for anyone seeking to understand these issues. Considering the U.S. role in European defence, inside and outside of the NATO framework, it is critical to understand what the implications may be if the United States focuses its military on the Indo-Asia-Pacific.
