Final answer:
Germany's theory behind aggressive conquest was driven by Hitler's ambition for Lebensraum and dominance over Eastern Europe, while the U.S.S.R. aimed to spread communism and protect against future invasions.
Step-by-step explanation:
The theory behind Germany and the U.S.S.R.'s aggressive conquest of Eurasia is complex and multifaceted. Both Germany and the U.S.S.R. had different motivations for their actions:
- In the case of Germany, Adolf Hitler's ambition to expand eastward and acquire Lebensraum (living space) for the German people was a key driving force. Hitler saw the lands of Eastern Europe, including Poland, as territories where Germans could settle and establish dominance over supposedly inferior populations.
- The U.S.S.R., on the other hand, sought to spread its economic and political systems to other nations and establish Communist governments. Joseph Stalin aimed to expand Soviet influence and protect the USSR from future invasions.
Both nations viewed each other as aggressive and committed to global domination, which further fueled their conquests in Eurasia.
