“No, Reagan was not a goofy idiot warning the world about the spacemen.”
He was not goofy, but he certainly did mention, in a press conference, the possibility of an invasion from outer space as a reason he would not abandon SDI, which is what Gorbachev demanded for an agreement.
Look it up if you don’t believe me. We have the internet now.
I’ve read it, I was alive then and since, and no one thought he was warning us of space alien threats.
Reagan used a common expression of how something outside of humanity that would threaten all of humanity would unify humanity into a common cause.
It is a common way of trying to convince people that we can unify today and have peace today if we just look beyond our differences or arguments.
Reagan was not warning us that Space Aliens are coming.
