In "Dead Wake: The Last Crossing of the Lusitania," author Erik Larson explores America's persistent isolationism through the observations of British journalist Sydney Brooks. Brooks argues that the United States, owing to its vast size, geographical advantages, and lack of strong neighboring adversaries, exists in a state of tranquility, untouched by the conflicts that plague Europe. This sense of remoteness fuels America's reluctance to engage in global disputes, emphasizing how isolationism is deeply ingrained in the nation's identity.

Brooks highlights that America’s position enables it to remain detached from the relentless politics and struggles affecting older, densely populated regions. The idea of neutrality, while seemingly straightforward, becomes complicated in the face of evolving global dynamics and the threats they pose. Larson's narrative draws attention to the broader implications of such isolationism during pivotal historical moments, encapsulating the tension between American ideals and the reality of international engagement.
