The funny thing is at this time, Stalin is directing his ire at the British and not listening to their warnings about Barbarossa, and he is not suspicious of Hitler, the one man in the world whom nobody should trust.

Maybe Stalin figured he was the only man in the world whom nobody should trust.

Funny, Homer. But that’s the irony of it all; Hitler was one person nobody should ever trust, and Stalin was probably the most paranoid ruler in the world who never trusted anyone...except the one person nobody should trust.
