If anything, USA, USSR, and Britain did most of the heavy lifting. US and UK defeated Japan and Italy, freed North Africa, and decimated the Germans at Bastogne, and even took major German Cities. The Soviets push the Germans back to Berlin and made Hungary, Romania, and Bulgaria switch sides. France, they did well. Saar offensive, defended France for 46 days, French Resistance and Free France, not to mention the help in D-Day.
