You beat me to it. When Brezhinski was Carter's advisor, I was in my early twenties. I was about as clueless and disinterested in politics as the next twentysomething, but this guy pinged my radar, hard.
I've never thought that he was anything but a commie infiltrator.
Zbig was known as a staunch anti-communist. Carter was criticized from the left for having him in his administration. Don’t ask me what happened.
What a crew back then huh? Stansfield Turner and the Halloween Massacre...gutting our own defenses.
