Overseas military bases have played a prominent role in support of United States security interests since World War II and particularly during the Cold War. While basing requirements have changed in the wake of the Cold War, it is clear that a forward US defense posture, including overseas bases and security partnerships, will remain essential to exert strategic influence, enable global access and project power when necessary. Globalization, fiscal constraints and the evolving threat landscape all present challenges to maintaining a network of forward bases. While it is important to assess overseas basing options in terms of operational requirements and value, their establishment and utility in times of crisis depend on host nation consent and support. Therefore, understanding host nation interests and concerns when it comes to the presence of US forces is critically important. Prompted by observations of the globalization phenomenon and an operational experience that highlighted the complexity of base hosting decisions, this study seeks greater awareness of the determinants of host nation hospitality. By examining overseas bases in Ecuador and Saudi Arabia that were ultimately rejected by those host nations and a third installation facing sharp opposition in Japan, the complex nature and relevance of host nation perspective is brought to light. These insights may inform future basing strategies as well as the diplomatic, military and economic engagement on which they depend.
