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.
> It is perfectly legitimate to critique someone's ideas.
I totally agree.
Anyway it's not "character assassination" if it's true. I don't know enough about this person's work over time but.
> always defending imperialism and the current power structure as the correct, natural and inevitable course of events, with no other alternative possible
That does describe some people I can think of, so it's at least possible this is a fair description of his position.
He's been playing that same song for decades. You already know what his position on everything is and how he'll argue for it. The real amazing thing is how much he's committed to it
