On October 1944, while Soviet troops liberate the city of Niš in Yugoslavia while advancing to Belgrade. Meanwhile, the USAF was bombing German-Albanian units in Kosovo. The US planes mistook the Soviet tanks as panzers and attacked them, which leads to the Soviets called for air support and a 5-minute dogfight ensues, until the Americans and Soviets backed off.
What if this turned into a war between USA/UK/France vs USSR? Who will win? Will Germany team up with the Allies?
