"Useful fools propaganda... since when has a commie state stabbed another in the back?"Like there was a little war between China and Vietnam in 1979, remember? Or the border clashes between USSR and China. Or Soviets invading their satellite communists states in Eastern Europe. Just because two nations are communist doesn't mean they can't have scores to settle.
"Or the border clashes between USSR and China."
I have read comments on FR that there are seismograph readings indicating that there were apparently small nuclear exchanges during part of this series of clashes.
