Answer: Germany was weakened and could not recover from how much effort it had expended in the Battle of the Bulge.
Explanation:
The Battle of the Bulge, also known as the Battle of the Ardennes, was an offensive attempt by German forces to push back the front line of Allied forces that had encroached into previously German-controlled territory. Winston Churchill is the one who first referred to the "bulge" that the Germans had pushed through into Allied forces.
The Germans were initially quite successful in their offensive. However, Allied forces managed to hold their ground after the initial "bulge" of the Germans. Eventually, the Allies pushed Germany's forces back. And the effort overall cost Germany too much. The Allies suffered about 75,000 casualties, but Germany lost 120,000 men and much military equipment and supplies. Germany was exhausting its strength. The overall result of the Battle of the Bulge was that it crippled and demoralized Germany's effort to continue against Allied advances.
The allies were set back acouple of weeks to regroup, resupply, and continue the advance. They defeated the Germans weeks after planned.
The Germans lost their gamble, and though they were able to keep the allies from offensive, they were never able to set up a proper defense because of losses, even less able to redouble their effort to continue the push.
The USSR was able to push through and get to Berlin, Germany first in the allied armies.
Germany had huge economical problems after the WWI and they are widely seen caused by the Versailles Peace treaty. Besides huge war debts Germany also needed to pay in total 132 billion marks of reparations for the Allies. Beginning from the 1921 Germany faced a huge inflation often referred as hyperinflation.
