The Generals

By Thomas E. Ricks

There’s a quiet question at the heart of The Generals: not how wars are won or lost, but how an institution learns from the people it puts in charge. What starts as a history of American generals slowly becomes something more unsettling. It’s about how accountability, once central to success, can fade away, and how the values that built an institution can erode over time.

The book follows American wars from World War II to Korea, Vietnam, and Iraq. It isn’t really about battles. It’s about leadership and how it changes. Ricks names people, traces decisions, and treats mistakes as real actions with real consequences. Across this long arc, he is tracking something bigger: how the U.S. Army rose to become a powerful, effective institution, and how parts of that foundation later weakened or were quietly abandoned.

Early on, George C. Marshall stands out as the architect of that success. During World War II, he builds a system that is demanding but fair. Generals are promoted quickly, but also removed quickly if they don’t perform. Many are relieved of command, not as punishment, but to keep the Army effective. Just as important, he builds a culture that values competence, honesty, and strong civil-military balance. This combination helps create an organization that can correct itself.

That system doesn’t last.

In Korea, the shift becomes visible. Douglas MacArthur dominates events, but his removal by Harry S. Truman shows something deeper. The military is no longer reliably holding its own leaders accountable. It takes presidential intervention. Leaders like Matthew Ridgeway can still turn things around, but the institutional habit of enforcing standards is weakening.

By Vietnam, that habit has mostly disappeared. William Westmoreland remains in command even as the strategy fails. The system no longer corrects mistakes. It absorbs them. Careers are protected, reputations are managed, and bad assumptions continue. The result is not just a failed war, but a failure of honesty within the institution itself.

Ricks frames this as a long decline from a high point. The Army that helped win World War II was built on clear standards and strong values. Over time, those values became diluted. Practices like removing underperforming leaders became rare, and the connection between performance and consequence weakened. The institution did not collapse, but it became less sharp, less self-aware.

After Vietnam, the Army reforms and improves in many ways. It becomes more professional and tactically capable. But something deeper remains off. The military grows better at executing operations than at questioning them. It can fight well, but struggles to connect those fights to clear strategic outcomes.

Another pattern keeps showing up. The military often wins the opening phase of wars quickly, but struggles with what comes next. This happens in Panama, Iraq, and Afghanistan. Early victories are fast and decisive, but the aftermath is poorly planned. The issue is not execution. It’s the lack of clear thinking about the end state. Plans exist for winning the war, but not for shaping what follows.

This tension becomes clearer in the late 20th century and the Iraq War era. Colin Powell emerges as a figure shaped by Vietnam’s lessons. His approach, often called the Powell Doctrine, stresses clear objectives, overwhelming force, and an exit strategy. It reflects an attempt to restore discipline and clarity to the use of military power. Yet even Powell’s influence cannot fully reshape the system, especially when decisions shift toward civilian leadership during wartime.

In the early 2000s, figures like Donald Rumsfeld and Dick Cheney play a dominant role in shaping the Iraq War. Ricks suggests that military leaders struggle to push back effectively. The old habit of candid internal dissent has weakened. Plans focus heavily on rapid victory, but give less attention to the aftermath. Once again, the question of what comes next is left unresolved.

Against this backdrop, David Petraeus appears as a partial counterpoint. His leadership during the Iraq surge shows adaptability and a renewed focus on strategy, especially around counterinsurgency and stabilizing conditions on the ground. But even here, the success is limited and temporary. It highlights both the possibility of strong leadership and the difficulty of overcoming deeper institutional patterns.

Throughout the book, individual generals illustrate this broader story. Dwight D. Eisenhower represents balance and adaptability. Maxwell Taylor reflects the risks of a system that rewards agreement over independent judgment. These examples build toward a larger point: leadership is shaped not just by individuals, but by the incentives and culture around them.

In the end, the argument is simple. The U.S. Army did not lose its ability to fight. It lost something harder to see. It lost the habit of holding its leaders accountable and of connecting battlefield success to meaningful outcomes. What remains is a powerful institution that can win battles, but too often struggles to decide what those victories are meant to achieve.
