The Wilopo Cabinet was something of a watershed in post-revolutionary Indonesian politics. During its fourteen months of existence important changes developed in the constellation of political power among the major political parties, the President, and the army. And within one of the major parties there occurred a shift in the relative strength of leadership groups of such importance as to bring about significant changes in the party's political posture and in its relationship with several of the other parties. It was during this period that cabinet government was seriously undermined and parliament lost much of its prestige and power; and it was during these fourteen months that were set in train many of the developments which have dominated Indonesian political life in the last few years.The key political events of this period are complex and confusing and have generally been but imperfectly understood outside of Indonesia. Yet failure to understand them can result in more than inability to understand the period itself. It will also make difficult any full and sound comprehension of the important developments of the past few years. Herbert Feith, in my judgment, has probed much further into the events of this period than any other non-Indonesian scholar. He has searched out a great deal of significant new data which he has analyzed with tools sharpened by long residence and research in Indonesia, interviews with many knowledgeable Indonesians and a full mastery of the Indonesian language. I believe he has presented as clear a picture of an important period of Indonesian history and of its shaping of subsequent events as is likely to emerge for some time. - George McT.
