I don't recall saying that Kennedy was good. The man practiced schizo-politics after all.Even Kennedy didn't listen to the RAND corporation, when they showed him the nukes on Cuba were actually completely insignificant in the global military balance (They didn't offer a new thread that wasn't already there from nukes from subs) and that starting a crisis about them would have a 10% risk of escalating in a nuclear holocaust. He still started the crisis for personal political reasons, namely to look strong after some earlier minor defeats in the Cold War. Now, you may say 10% is a small number, but it remains still a possible outcome, which he was to risk for political gain. There are only very few politicians (and people) who entirely understood the consequences of a nuclear war.
