Approximately half of the U.S. discretionary budget is spent on defense — nearly three times what any other country spends on defense. The defense budget has grown exponentially in recent years, and now exceeds the defense budgets of the next 10 countries combined, many of which are U.S. allies. The Center for Arms Control and Non-Proliferation works to transform our national security spending and strategies to better meet the threats of the 21st century, promote increased oversight of the U.S. defense budget, and prioritize non-military solutions to conflict.
