This is not a new problem for the US, whose constitution is based on the eighteenth-century liberal view that power is best controlled by fragmentation and countervailing checks and balances, with the president and Congress forced to compete for control in areas like foreign policy. In other words, the US government was designed to be inefficient, in order to ensure that it could not easily threaten the liberty of its citizens.
这并不是美国的新问题，美国宪法的基础是十八世纪自由观——控制权力最好的办法是分散化和对抗性制衡，迫使总统和国会为控制外交政策等领域而斗争。换句话说，美国政府是以低效为目的设计的，这样做是为了确保它不会轻易威胁公民的自由。
