When Congress Remade the Pentagon

The Goldwater-Nichols Act at Forty.

The full paper is available here.

Military victories are won by commanders and the troops they lead. But the preparation for those battles begins years before a bullet is ever fired—even in the committee rooms of Congress, as it did forty years ago.

Every American who watched Operation Desert Storm, the opening days of Operation Iraqi Freedom, or the 2011 raid that killed Osama bin Laden witnessed a military that appeared almost effortless in its coordination. So did the nation that watched Operation Absolute Resolve unfold in January 2026, when Navy, Air Force, Space Force, Marine Corps, and Army special operations forces converged in a single, seamless raid to capture Venezuelan strongman Nicolás Maduro. Orders flowed through a clear chain of command. Forces from every service operated under unifi ed leadership. Commanders understood their authorities. The military had been trained to act as members of a joint force. Those features of the modern American military seemed so natural that many Americans rightly assumed it had always been that way. But the truth of the matter is, it has not.

Forty years ago, the Department of Defense remained organized largely as it had been after World War II—a collection of individual military services that trained separately, planned separately, purchased separately, and, too often, fought separately. The results were a string of failures. Reform commissions came and went. Secretaries of Defense proposed changes that were blocked. Senior officers acknowledged the shortcomings but vigorously defended their institutional and parochial prerogatives.

Large organizations rarely redistribute their own authority voluntarily. The Pentagon proved no exception. For more than a generation, meaningful reform proved impossible. Then Congress did something extraordinary.

In 1986, over the strong objections of the Pentagon’s senior civilian and military leadership, the Senate Armed Services Committee (SASC) and the House Armed Services Committee (HASC) in a bipartisan approach, enacted the most sweeping reorganization of the American military since the National Security Act of 1947. Over the course of just a handful of months, the legislative culmination of years of staff preparation, hearings, and analysis—the Goldwater-Nichols Department of Defense Reorganization Act, the Nunn-Cohen Amendment establishing U.S. Special Operations Command, and the acquisition reforms inspired by the Packard Commission—were all written into statute and permanently changed how the United States commands, equips, and employs military force.

As Staff Director on the SASC at the time, I watched senators from both parties confront a Department whose own organizational structure had become the problem—and whose civilian and military leaders were unwilling to address their own failures. Today, four decades later, every major American military operation still rests on the foundations Congress built during that remarkable legislative period. Today’s Chairman of the Joint Chiefs of Staff , General Dan Caine, put it plainly after the Venezuela operation: “What we’ve witnessed today is a powerful demonstration of America’s joint force.” That kind of statement would have been unthinkable forty years ago.
