That's the exact sentence, and it doesn't sit right with me for three distinct reasons.
First, it can be read as an an implication: "these 4 countries where part of the "third world" and now aren't given their post-war trajectory." which ignores the history of those 4 nations long before WWII or Western involvement.
Second, makes the same a-historical mistake by assuming that the particular path followed by those nations can readily be transposed towards other regions in the world.
Third, it's a take that ignores the agency other cultures and peoples have to carve out their own place in the world. Moreover, many of the problems in the so-called global south are a direct result of this exact thinking. Countless cultures and ways of living have disappeared over the past 2 centuries because it.
