It was a mistake.
Mistake which gave fruit later on.
Due to Warsaw Rising, Soviets delayed their offensive until January next year. Nearly 5 months!
Why was it important? In this time, US-Anglo allies liberated Western Europe and started conquering Germany proper. Until May 8, the unconditional surrender of the Third Reich, they captured half of it, which soon became the democratic German republic. Soviets captured the other half.
Can you imagine how difficult it would be for the West to win the Cold War with the USSR if they controlled whole Germany and turned it into Soviet German totalitarian state like they did in its Eastern zone of occupation???
Thanks to Warsaw`s sacrifice, it didn`t take place and eventually the evil state, USSR, was defeated and collapsed.
Salute to Warsaw insurgents!
