Published each year since 1959, The Military Balance is an indispensable reference to the capabilities of armed forces across the globe. It is used by academia, the media, armed forces, the private sector and government. It is an open-source assessment of the military forces and equipment inventories of 171 countries, with accompanying defence economics and procurement data. Alongside detailed country data, The Military Balance assesses important defence issues, by region, as well as key global trends, such as in defence technology and equipment modernisation. This analysis is accompanied by full-colour graphics, including maps and illustrations. With extensive explanatory notes and reference information, The Military Balance is as straightforward to use as it is extensive. The 2022 edition is accompanied by a fullcolour wall chart illustrating security dynamics in the Arctic.

A RAND study analyzed Chinese and U.S. military capabilities in two scenarios (Taiwan and the Spratly Islands) from 1996 to 2017, finding that trends in most, but not all, areas run strongly against the United States. While U.S. aggregate power remains greater than China’s, distance and geography affect outcomes. China is capable of challenging U.S. military dominance on its immediate periphery—and its reach is likely to grow in the years ahead.

Defense Budget Increases: How Well Are They Planned and Spent

U.S. defense spending isn’t excessive and, in fact, should continue to grow because it’s both affordable and necessary in today's challenging world. The United States spends a lot of money on defense—$607 billion in the current fiscal year. But Brookings national security scholar Michael O'Hanlon argues that is roughly the right amount given the overall size of the national economy and continuing U.S. responsibilities around the world. If anything, he says spending should increase modestly under the next president, remaining near 3 percent of gross domestic product. Recommendations in this book differ from the president's budget plan in two key ways. First, the author sees a mismatch in the Pentagon’s current plans between ends and means. The country needs to spend enough money to carry out its military missions and commitments. Second, O'Hanlon recommends dropping a plan to cut the size of the Army from the current 475,000 active-duty soldiers to 450,000. The U.S. national defense budget is entirely affordable—relative to the size of the economy, relative to past levels of effort by this country in the national security domain, and relative, especially, to the costs of failing to uphold a stable international order. Even at a modestly higher price, it will be the best $650 billion bargain going, and a worthy investment in this country’s security and its long-term national power.

They were four exceptional soldiers, a new generation asked to save an army that had been hollowed out after Vietnam. They survived the military's brutal winnowing to reach its top echelon. They became the Army's most influential generals in the crucible of Iraq. Collectively, their lives tell the story of the Army over the last four decades and illuminate the path it must travel to protect the nation over the next century. Theirs is a story of successes and failures, of ambitions achieved and thwarted, of the responsibilities and perils of command. The careers of this elite quartet show how the most powerful military force in the world entered a major war unprepared, and how the Army, drawing on a reservoir of talent that few thought it possessed, saved itself from crushing defeat against a ruthless, low-tech foe. In The Fourth Star, you'll follow: •Gen. John Abizaid, one of the Army's most brilliant minds. Fluent in Arabic, he forged an unconventional path in the military to make himself an expert on the Middle East, but this unique background made him skeptical of the war he found himself leading. •Gen. George Casey Jr., the son of the highest-ranking general to be killed in the Vietnam War. Casey had grown up in the Army and won praise for his common touch and skill as a soldier. He was determined not to repeat the mistakes of Vietnam but would take much of the blame as Iraq collapsed around him. •Gen. Peter Chiarelli, an emotional, take-charge leader who, more than any other senior officer, felt the sting of the Army's failures in Iraq. He drove his soldiers, the chain of command, and the U.S. government to rethink the occupation plans–yet rarely achieved the results he sought. •Gen. David Petraeus, a driven soldier-scholar. Determined to reach the Army's summit almost since the day he entered West Point, he sometimes alienated peers with his ambition and competitiveness. When he finally got his chance in Iraq, he–more than anyone–changed the Army's conception of what was possible. Masterfully written and richly reported, The Fourth Star ranges far beyond today's battlefields, evoking the Army's tumultuous history since Vietnam through these four captivating lives and ultimately revealing a fascinating irony: In an institution that prizes obedience, the most effective warriors are often those who dare to question the prevailing orthodoxy and in doing so redefine the American way of war.
