Tuhia he whakamāramatanga mō tēnei wāhanga - I takahia e Tiamana te Tiriti o Molotov<unk>Ribbentrop, ā, i whakaekehia te Soviet Union i te 22 o Pipiri 1941 e tīmata ana i te mea i mōhiotia i te USSR ko te Pakanga Matua Nui. I whakamutu te ope Whero i te ope Tiamana i te Pakanga o Moscow. Ko te Pakanga o Stalingrad, i roa mai i te mutunga o te tau 1942 ki te timatanga o te 1943, i tino werohia a Tiamana kaore i tino ora mai, a ka waiho hei takahanga i roto i te pakanga. Whai muri i a Stalingrad, ka haere nga ope Soviet i Ūropi ki te Rāwhiti ki Berlin i mua i te hekenga o Tiamana i te tau 1945
He aha? I mate te 80% o te ope taua Tiamana i te Rāwhiti. I korero a Harry Hopkins, he kaitohutohu piri ki te kaupapa here a Franklin D. Roosevelt, i te 10 o Akuhata 1943 mo te mahi nui a te USSR i te pakanga.
