Read the most recent analysis from CSIS experts on defense-related issues.
The National Defense Strategy calls for “modernization of key capabilities through sustained, predictable budgets,” yet the unclassified summary and FY 2019 budget request fail to show how the Department of Defense will fund such a priority in the face of long-term, strategic competition with China and Russia.
Analysis of the FY 2019 Defense Budget provides an in-depth assessment of the Trump administration’s defense budget request for FY 2019 in addition to analyzing the Department of Defense’s projections for the future and long-term trends in defense funding levels and force structure.
Acquisition Trends 2018: Defense Contract Spending Bounces Back analyzes the current state of affairs in defense contracting at a time when the defense acquisition system sits at an inflection point. Defense contracting has rebounded these past two years, but there are unanswered questions about continued defense budget growth and the long-term effects of the last few years’ acquisition reform efforts.
Discussion over transatlantic security spending has increasingly focused on whether NATO members are spending 2% of their GDP on defense and the merits of 2% as a metric for assessing burden sharing. In addition to analyzing current NATO metrics, this report examines several alternatives that provide a broader understanding of collective security contributions and could improve the rigor of security spending analysis.
The official 2 percent threshold, while mandated at the 2014 Wales Summit, has long been understood as an unofficial spending target for NATO members. According to 2017 estimates illustrated in the graphic, only four of the 28 NATO member states meet the 2 percent spending level while 15 are expected to meet it by 2024..
NATO breaks defense expenditure into four main categories: equipment, personnel, infrastructure, and other. In addition to the commitment to spend 2 percent of GDP on defense, NATO heads of state pledged at the 2014 Wales Summit to spend 20 percent of their defense budgets on major equipment.
As some allies and partners call for a broader view of the investments that contribute to collective defense, the CSIS study team examined security assistance spending by NATO member states and its select subset of European partners.
The CSIS report compiles NATO member and partner countries’ troop contributions across a range of military operations. Where data was publicly available and reliable, it measures troop contribution as a percentage of the total active duty force to normalize and compare between countries with militaries of different size.
Most measures of security contribution focus on investment. But states also forego economic gains in support of common security. The effect of enforcing agreed upon sanctions against a potential adversary is one metric that could be used to measure this sacrifice.
