I'll do you one better.

I'll point to the picture the Doctor posted, the one where the President (FDR) gave the bad guy entire regions of Europe which he used to enslave millions, build up his military, point missiles at us and generally engage in the same sort of nasty business that the guy they'd defeated was working on.

Does that picture mean that the U.S. was forever prevented from standing up to the USSR once we figured out what a bastard Stalin was? Does that mean that Jack Kennedy was a hypocrite or somehow at fault for the Cuban missile crisis simply because his father was in the same administration as Roosevelt?

Similarly, those pictures of Clinton and Carter show U.S. presidents being photographed with Middle Eastern leaders who were known, or later discovered to be, "bad guys." One of whom, Arafat, was deeply involved in formenting Islamic terrorism.

Does the mere fact a member of the administration, or even the president himself, is photographed being cordial with another nation's leader, who is an asshole, mean the president is somehow complicit in that other leader's evil schemes?

By your logic, yes. By the real world's logic, no.
