Actually the US has mismanaged capitalism, I can’t argue with him there. He’s a respected foreign policy academic and not associated with any partisan views or attachments. The fact that you resorted to argumentum ad hominin to dismiss him means you have no argument against what he says.
My complaint about him is that in general he is not critical of Russia but is very critical of the US.
He’s a smart guy; but on this subject (Russia, Ukraine, US) he is fully on Russia’s side, and I don’t agree with his reasons.
That’s not an ad hominem (BTW: It’s spelled with an “e,” not a second “I”). I just happen to think he is biased in favor of Russia.
He also said this about Trump:
“It’s obvious that Trump did something wrong,” said John Mearsheimer, professor of political science at the University of Chicago and an expert in international relations. “The actual use of American power to gain leverage over a country or to coerce another country is done all the time. What’s special about this case is that it was done for the purpose of influencing domestic politics. It was done with the purpose of helping Trump win the 2020 election.”
