Nikita Sergeyevich Khrushchev (18941971)
They say that the Soviet delegates smile. That smile is genuine. It is not artificial. We wish to live in peace, tranquility. But if anyone believes that our smiles involve abandonment of the teaching of Marx, Engels and Lenin he deceives himself poorly. Those who wait for that must wait until a shrimp learns to whistle.
