波大的意思是可见美中当时事实上不平等。 hkzs的解释说，那是美中两国当时的协议，这个看法看来比较靠谱。
问copilot，美军驻扎在欧洲也实际上享受某种程度的“治外法权”。美军在执行命令和完成值守（on duty）期间被指控犯罪由美军军事法庭审判，而不是所在国家。而且即使所在国有权审判，也常常转交美军处置。
所以，波大的“治外法权”论，不能简单视为不平等的证据。
Who Has Jurisdiction When a U.S. Soldier Commits a Crime in Europe?
Short answer:
Both the host nation and the United States have jurisdiction.
Under the NATO Status of Forces Agreement (SOFA), the host country has primary jurisdiction over crimes committed off?duty, while the U.S. military retains primary jurisdiction over offenses arising from official duty. In practice, the two governments coordinate, and many cases are handed over to U.S. military courts。
