Synopsis
The Kings of War: How Our Modern Presidents Hijacked Congress’s War-Making Powers and What To Do About It by Scott S. Barker is a meticulously researched exploration of how the balance of war-making authority in the United States has shifted dramatically from Congress to the presidency, undermining the constitutional framework established by the nation’s founders. Barker, a former military intelligence officer and accomplished civil trial lawyer, argues that the U.S. Constitution explicitly grants Congress the sole power to declare war, a deliberate design by the framers to prevent the executive from unilaterally committing the nation to conflict, as was common under monarchial systems like that of England. However, beginning with President Harry Truman’s decision to engage in the Korean War without congressional approval, modern presidents have increasingly asserted an “inherent” authority as commanders-in-chief to initiate military actions, effectively rendering themselves “kings of war.” This power grab, Barker contends, has fundamentally altered the constitutional balance, creating an executive-centric government where the president’s war-making decisions often bypass legislative oversight, with profound implications for American democracy and national security.
The book begins by delving into the historical context of the Constitutional Convention, where the framers carefully debated and designed a system to divide war-making responsibilities. Congress was given the authority to decide whether the nation should go to war, while the president was tasked with conducting wars once authorized, subject to Congress’s control over funding. Barker illustrates this original intent through an in-depth examination of the Northwest Indian War during George Washington’s administration, the first conflict fought under the Constitution. Washington, who presided over the Constitutional Convention, adhered strictly to the principle that Congress held the authority to authorize war, consistently seeking legislative approval for resources to conduct the campaign. This historical precedent serves as a benchmark for Barker’s analysis, highlighting how far the modern presidency has strayed from the founders’ vision.
Barker traces the erosion of congressional war powers through key historical moments, with a particular focus on the post-World War II era. He identifies President Truman’s unilateral commitment of U.S. troops to the Korean War in 1950 as a pivotal turning point, marking the beginning of a trend where presidents claimed independent authority to engage in military conflicts. This trend continued through the Cold War, the Vietnam War, and culminated in President George W. Bush’s aggressive assertion of executive war powers during the 2003 invasion of Iraq. Barker also dedicates a chapter to the unique challenges posed by nuclear weapons, which have further complicated the war powers dynamic due to their instantaneous and catastrophic potential, often cited as justification for expanded presidential authority. Through these case studies, Barker demonstrates how presidents have exploited ambiguities in their commander-in-chief role, often with Congress’s acquiescence, to expand their war-making powers.
The book concludes with an analysis of the factors that have enabled this shift, including congressional reluctance to assert its constitutional authority, public apathy, and the increasing complexity of modern warfare. Barker argues that this imbalance has led to a dangerous concentration of power in the executive branch, undermining democratic accountability. To address this, he proposes a legislative agenda to restore the constitutional balance, including reforms to close loopholes in the 1973 War Powers Resolution, which allows presidents a 60- to 90-day window to engage in military action without congressional approval. He also advocates repealing outdated Authorizations for Use of Military Force (AUMFs), such as those from 2001 and 2002, and passing legislation to require explicit congressional authorization for the first use of nuclear weapons. Additionally, Barker suggests that the costs of military actions should be borne by current taxpayers rather than deferred as debt, ensuring broader public accountability. Written in accessible prose, the book combines scholarly rigor with engaging historical narratives, making a compelling case for reining in presidential war powers to realign with the Constitution’s original intent.
