Rokossovski was subjected to torture during the Stalinist purge
He was subjected to extreme hounding and humiliation.
His wife and children were sent into internal exile.
Himself, he was pressured to sign all nature of false confessions which were popular at the time. The price for not signing these confessions, was inhuman beatings and other forms of torture.
He never ratted anyone out. He never confessed. Then, when the time came, and the country came calling - he answered the call.
This is a patriot of Russia.
Russia brutalized him and spat in his face, trampled over everything he held dear, and yet he went out there and laid his soul down for the defense.
This makes Rokossovski more Russian than most Russians.
