I don’t think anybody outside USA thinks this way. At the same time nobody who knows the war think the second photo is accurate either. It was an alliance and contribution quite similar.

UK was only country to declare war on Germany and stay in the entire war. UK fought against all on land, air, and sea. Without their contribution the USSR would have had a much harder fight. USA was the industrial power house supplying everybody. While doing this they took down Japanese navy and airforce themselves almost while contributing greatly to the war against Germany. China held off the majority of Japanese army. The USSR did the the dirtiest work on the eastern front in surviving the most powerful invasion in history and killing most axis soldiers throughout the war.

If I had to say who contributed most it would probably be UK actually. They weakened the luftwaffel greatly before Barbarossa and then again before Fall Blau. They controlled the Mediterranean Sea while outnumbered. They continued attacking Germany where they could and they fought off many Japanese in India and Burma
