The United States is considering reducing the number of troops stationed in Germany, amid a dispute with Berlin over the Iran war. The U.S. had just over 36,000 active-duty military personnel across 20 bases in Germany as of December 2025. The move could be a significant blow to NATO allies in Europe, who value the U.K. presence as a significant deterrent against threats like Russia. This comes as relations with Germany's Chancellor, Chancellor Friedrich Merz, have worsened due to comments he made about the Iranian regime's behavior.
