As I see it, there were three nations that tried to profiteer from WW2; Germany, Japan, and the USSR. Ultimately none of them did. Germany suffered occupation and complete social collapse, Japan got occupied and pasted in radioactivity, and the Soviet Union ended up with huge areas devasted, a significant portion of dead people, and the war cemented the corrupt systemic power structures focusing on heavy industry and military power, issues Russia still struggles with. The British lost an empire, and was indebted up to the rafters. While the US and Australia could be said to have profited, they in no way were profiteering. Profiteering is well beyond reasonable recompense (profit).
