Despite the withdrawal of U.S. military bases and troops from Afghanistan, the United States continues to maintain approximately 750 military bases abroad in 80 foreign countries and colonies (territories). These bases are costly in a number of ways: financially, politically, socially, and environmentally. U.S. bases in foreign lands often raise geopolitical tensions, support undemocratic regimes, and serve as a recruiting tool or militant groups opposed to foreign military occupation and governments bolstered by U.S. installations. In other cases, foreign bases are being used and have made it easier for the United States to launch and execute disastrous wars, including those in Afghanistan, Iraq, Yemen, Somalia, and Libya. Across the political spectrum and even within the U.S. military there is growing recognition that many overseas bases should have closed decades ago, but bureaucratic inertia and misguided political interests have kept them open.
Amid an ongoing “Global Posture Review,” the Biden administration has a historic opportunity to close hundreds of unnecessary military bases abroad and improve national and international security in the process.
The Pentagon, since Fiscal Year 2018, has failed to publish its previously annual list of U.S. bases abroad. As far as we know, the full “Drawdown” report presents the fullest public accounting of U.S. bases and military outposts worldwide. The lists and map included in the full version of the report illustrate the many dangers and problems associated with these overseas bases, offering a tool that can help policymakers plan urgently needed base closures.
