What's his name (I decline to use his nickname, because as far as I'm concerned he isn't) says: "My critics are the one's who have failed to name a single major battle in the Pacific won by non-Americans." How about the British 14th Army, and specifically the 5th Indian Division's defeat of the Japanese 15th Army in Assam (March-June 1944) and General Wingate's campaign in Burma?

The large amount of US aid was certainly a major factor in Russia's victory in the east, but much of it was transportation assets. It is really unlikely that much Soviet artillery ammunition came from US plants, both because the supply lines were too long and dangerous for cargo space to be wasted on expendables such as munitions and because the standard Soviet field artillery pieces were different calibres (76.5mm, 122mm and 152mm) than American (75mm, 105mm, 155mm and 8").
