Boris Shcherbina: OF COURSE I know they're listening! I want them to hear, I want them to hear it all! Do you know what we're doing here? Tell those idiots what they have done!
[beat]
Boris Shcherbina: I DON'T GIVE A FUCK!
[beat]
Boris Shcherbina: Tell them, go tell them! Ryzhkov! Go tell Ligachyov! Tell fucking Gorbachev! Tell them!

Boris Shcherbina: The official position of the State is that a global nuclear catastrophe is not possible in the Soviet Union. They told the Germans that the highest detected level of radiation was 2,000 roentgen. They gave them the propaganda number. That robot was never going to work.
[to a nearby soldier]
Boris Shcherbina: We need a new phone.
