In the debate over the United States’ role as the “indispensable nation” in shaping global order. Robert J. Lieber debates whether this role remains necessary and possible in a post-Cold War world, where the United States became a global leader in economy, technology, culture, and military power. For that matter, he identifies key internal and external challenges that have emerged and reshaped the present international scenario. Externally, he scrutinizes the consequences of 9/11, the rise of revisionist powers, nuclear proliferation, and the erosion of expertise. Internally, the challenges derived from wars in Afghanistan and Iraq and the hesitations in Syria, which significantly questioned America’s credibility and its ability to engage effectively in Foreign Affairs. In his discussion, Lieber acknowledges a small reduction in the United States’ weight on the world stage, especially with all the global changes. However, he staunchly contends that despite these transformations, America’s “unmatched strengths” still make its role in shaping a stable and prosperous global environment crucial.
