Probably, the reviewer is refering to the fact that the book is critical of US policy. Well, if that's "Stalinist", then this book is "Stalinist". But, most people would agree that dissenting with the policies of a country has nothing to do with "Communism" or sympathizing with Stalin, and a lot more to do with being honestly concerned with the injustices and atrocities abound in the world and laying them down in front of the very people they've been concealed from.
That's what this book is all about. And I think it is right to do so.
One common motif of the book is 'stability' as coveted above all by American interests and how different overt and covert means are imposed upon different countries to achieve it.
The Washington Connection... is a brilliant foray into parts seldom travelled by popular media and recommended.
