Louis Henkin

Reviews the constitutional relationship between the US president and Congress in the area of foreign affairs, and of war and peace in particular. There is a sizeable twilight zone of concurrent authority. Reviews constitutional developments and considers their implications for war powers, nuclear strategy, spending powers, covert actions and treaty-making. Notes that the USA is a republic which has become a democracy, and concludes that although the president provides leadership, Congress represents the people, so that "good government as well as democracy demands fewer decisions by one representative alone, for war or in peace."
