While U.S. defense policy contends that BMD strengthens alliances, the historical record is mixed; sometimes BMD has bolstered alliances, but other times it has exacerbated allies’ doubts about U.S. commitment. When determining BMD policy and investments, U.S. leaders should consider not only expected defensive benefits but also how their decisions might affect allies’ perceptions of alliance cohesion and credibility.
