Who supported German aggression in Europe?

German aggression in Europe during the early 20th century, particularly leading up to and during World War II, was supported by various factions, including the Nazi Party under Adolf Hitler, which promoted aggressive nationalist and expansionist policies. Additionally, some segments of the German military and industrial sectors backed these ambitions, seeing the potential for territorial expansion and economic gain. Furthermore, alliances with countries like Italy and Japan, as well as sympathizers in other nations, also contributed to the support for German expansionism.
