What were the issues surrounding eisenhower's decision not to push to berlin?

Eisenhower himself gave three reasons not to push on to Berlin:

His armies were already well beyond the line agreed upon with the Soviets for the Western occupation zones.  He did not want to offend Stalin and knew that any added territory taken would be handed over to Soviet control.

He had some concerns about his troops meeting Soviet troops if both were pursuing the same goal.

Berlin was only a political objective, not a military objective, General Eisenhower said.  

It also was a factor that one of Eisenhower's field commanders had estimated that for US troops to take Berlin could cost as many as 100,000 casualties.  The Soviet armies bore the cost.  30,000 Soviet soldiers died in the Battle of Berlin.
