We supplied Russia with materials so they could even stay in the fight. In the meantime, the USA single-handedly took down the Imperial Japanese, which Russia should also thank us for.
Yup Russia rolled in the end to claim territory and “victory”
Aussies beat the Japanese in the fist victory jungle land battle of the war for Bougainville.They were civilians drafted in a hurry. The Japanese never recovered. All they had was air power and some land forces but Guadalcanal Marines stopped that real quick.
Russians drove Germany out of their country, and pushed them back before America even entered the war. If Russia hadn’t been able to do that, the war might have ended differently.
