No - why do you say that?

PP is attacking Fukuyama _based on his ideas_ - that imperialism is the natural course of events, the best for everyone, and inevitable. It is perfectly legitimate to critique someone's ideas.

That is the reverse of ad hominem. A ad hominem argument would go, "Fukuyama is wrong because he's from Harvard/Asian/etc", and of course those arguments are false.
