Patton may have wanted to go for the Soviets, I doubt very much the troops who had fought from North Africa to Germany wanted to. Why should they when they have been told the Russians were our allies?
Correct
At that point in the war it would have been totally insane to attack one of our allies, specially since we didnt have the forces in theatre to have the slimmest hope of winning.
The Pacific Front was reaching it's zenith and the Soviets had already agreed to move forces East to help us once the German offensive was over.
And well they did.....
