All Red Germany

WI the Battle of the Bulge had been more successful, delaying the Anglo-Americans enough so that the Soviets get to take, at horrendous cost, all of Germany up to the Rhine. At such a cost, that national pride & honour will on no account allow Stalin to split Germany as agreed at Yalta. Austria is returned to the west. But the Soviets are adamant: not Germany. Short of going to war, how would the US & free Europe react to a DDR bordering Holland, Belgium, France and Denmark, & how would it have influenced the subsequent 30 years?

A longer, costlier Battle of the Bulge would have (probably), would have delayed the Yalta Conference. Yalta would have happened in March, by which time there's a good chance that the added anxiety and pressure of the stalled Allied advance would have killed Roosevelt. Yalta would have been more ably handled by President Truman.

Thus, less would have been granted to the Soviets. If, however, the Soviets were granted German land on the east bank of the Rhine (which I think is highly unlikely), it might be that: A) someone like Patton would have started a war, B) Churchill might have walked out at Yalta, and C) German commanders would have surrendered to western Allied forces as soon as Berlin fell.
