If you were a German in 1938 and two Wermacht soldiers were accused of spying for the USSR, you would be saying the exact same thing as you are now. I say this not as a dunk, but as a solemn acknowledgement that we are all products of our social environment. I don't think you're stupid, or a "bad person" (whatever that means) but I do think you should stop and consider the path that uncritically accepting your government's narratives about their rivals can lead you down.
