Soviet forces are often criticized for not supporting the Warsaw uprising in WW2 for political reasons (to eliminate Polish rivals etc.) However I have also read a conflicting viewpoint that states the Red Army was not in a position to cross the Vistula.
So, what is the consensus today among historians? Did the soviets stop short of Warsaw for political or military reasons? And what are the evidence for both sides?
Here's a response from /u/Georgy_K_Zhukov that gives good details about Soviet-Polish relations and the goals of the Soviet Union at the time.
