For the purpose of this question, the United States includes all its land and sea territory. A fusion reactor counts if it's controlled by the federal US State, a local or foreign enterprise, or a foreign nation (but not a foreign nation's military). However, any construction, use, or ownership change must be freely approved by the United States. Reactors built or used without the permission of the USA, or by foreign military, don't qualify in the context of this question.
