The Overseas Base Realignment and Closure Coalition, “a group of military base experts from across the political spectrum,” is calling on Congress to mandate a reporting requirement on overseas bases. In a letter to the Senate and House Armed Services Committees, the group of experts says the information that the Department of Defense currently provides on the cost and location of overseas bases is very “limited” and the “data is frequently incomplete.” This lack of transparency, they write, has allowed the Pentagon to erroneously claim America’s empire of overseas military bases — some 800 installations in 70 or 80 countries around the world — only costs taxpayers $20 billion per year, even while more inclusive independent estimates go as high as $150 billion per year. Below is an excerpt of the letter:

Research has long shown that overseas bases are particularly difficult to close once established. Often, bases abroad remain open due to bureaucratic inertia alone. Military officials and others frequently assume that if an overseas base exists, it must be beneficial; Congress rarely forces the military to analyze or demonstrate the national security benefits of bases abroad.


The Navy’s “Fat Leonard” corruption scandal, which resulted in tens of millions of dollars in overcharges and widespread corruption among high-ranking naval officers, is one of many examples of the lack of proper civilian oversight overseas. The military’s growing presence in Africa is another: When four soldiers died in combat in Niger in 2017, most members of Congress were shocked to learn that there were approximately 1,000 military personnel in that country. Although the Pentagon has long claimed it has only one base in Africa—in Djibouti— research shows that there are now around 40 installations of varying sizes (one military official acknowledged 46 installations in 2017). You are likely among a relatively small group in Congress who know that U.S. troops have been involved in combat in at least 22 countries since 2001, with frequently disastrous results.


Current oversight mechanisms are inadequate for the Congress and the public to exercise proper civilian control over the military’s installations and activities overseas. The Pentagon’s annual “Base Structure Report” provides some information about the number and size of base sites overseas, however, it fails to report on dozens of well-known installations in countries worldwide and frequently provides incomplete or inaccurate data. Many suspect the Pentagon does not know the true number of installations abroad.

A proposed provision in the 2020 National Defense Authorization Act (NDAA) called “Report on Financial Costs of Overseas United States Military Posture and Operations,” could, “if implemented rigorously,” the letter writers say, “increase transparency and enable better oversight over Pentagon spending, contribute to critical efforts to eliminate wasteful military expenditures, and enhance military readiness and national security.”
