Question

WWI and WWII were similar in that the main cause of each was

a. arms races. b. alliances or c. aggression of strong powers against smaller states

Can't figure out which is the BEST answer

Answer 1

What the short term causes of the First and Second World Wars have in common is the aggression of strong powers against smaller states. The outbreak of World War I was the result of the Austro-Hungarian Empire's insistence on invading and eliminating Serbia - the aggression of a strong power against a smaller state. The outbreak of World War II, in Europe at any rate, was the result of Nazi Germany's insistence in invading and eliminating Poland - the aggression of a strong power against a smaller - or at least weaker - state.
