Answer:
The rise of totalitarianism lead to World War II because the leaders of totalitarian countries were empowered to pursue militant goals without opposition within their own countries. Dissent is not tolerated in totalitarian regimes, which means totalitarian governments are not accountable to the people like they would be in a democracy. Once in power, totalitarian leaders, such as those in Japan and Nazi Germany, were free to try and expand their power by aggressively waging war and invading other territories, and the aggressive actions of these leaders led directly to the start of World War II.
