Mandela or Hitler are don't seem particularly anti-American.

I suppose I didn't pick the best examples. Though Mandela was a critic of the US in later years regarding Iraq / Israel, and Hitler's sentiment on America seems to be complex: a combination of not taking america too seriously and not desiring conflict too early.
But I don't think that changes my original point, which is that all dictators can be seen as serving their people, depending on how you define "their people".
I don't disagree, but the comment you replied to was about the direct correlation between "the amount of anti-American rhetoric" and "how much they screw their country over" so the fact that you choose as example dictators which were not very high in the anti-American rhetoric axis kind of supports his case.
