Yalta Conference and Poland [78]
for what price was Poland sold?
For 1 million dead soviets in eastern european theatre,Austria,Finland and half of Berlin.In fact Poland was sold in a package with Hungary but Poland was a special case since it was an allied state while Hungary had actively participated in Wehrmacht operations so its fate was sealed.
For Poland Stalin threatened to freeze the eastern front and cause hundreds of thousands of western soldiers to die,so really UK and USA had no alternative.
