The general thesis is excellent, in sum a prescient analysis of the new international order, above and beyond the old nationalisms, and the intensifying process of economic globalization, but the particular dynamics detailed in Ward's tripartite examination of the disparities in politics, wealth, and ideology, are all geared towards the cold-war preoccupations of mid-late 1960s Western powers. This would have been essential reading 40 years ago, and still has some relevance today, mostly as historical background into the economic dynamism of the inter- and postwar years and indicative of the processes of global economic and political power that has led eventually to today's current configuration.
Many of the problematics Ward highlights, including the question of national self-determination/sovereignty, the spread of regional economic blocs as steps towards the global unity, and the relevance of the UN, as opposed to the opportunities it presents, are still manifest as pressing issues of our own raging times. At the same time, the aforementioned preoccupation with Cold War Realpolitik and a rather naive (though prevalent at the time) view of the scope and role of international development assistance are definitely artifacts of the milieu of which it is part. It should get 3.5 stars, if possible.
