The second edition of this pathbreaking, highly innovative comparative study in state-building by a major political scientist is a fully updated examination of the problems of making democratic government work. He concludes with a detailed proposal for a new type of government: alternating presidentialism. This meets the need for strong parliamentary control and efficient government, with safeguards against both parliamentary obstructionism and government by decree, and so could help to avoid political paralysis in Latin America, in the post-communist countries of Europe and in countries with dysfunctional parliamentary systems such as Italy and Israel.
