Dictators often have megalomania.

ok, so crazy or huge ego's right? Sounds like North Korea person.

They did not act alone. they were encouraged by many wealthy financiers. Fritz Thyssen (a member of I.G. Farbin Industries A.G.)was one of Hitlers first backers. Media supported him, He was Time magazine's Man of the year, TWICE! (before the war).

Emperor Hirohito Came from a family of rulers who all Japanese people thought were actual gods.

This is a huge subject, best addressed by Dave Emory, Google his name, or Spitfirelist for his analysis of fascism and its causes.

In World War 2, several dictators, such as Adolf Hitler, Benito Mussolini, and Emperor Hirohito, had ambitions to expand their territories and establish hegemony over Europe and other regions. Their motivations varied, but some common factors contributed to their belief that they could take over Europe and other places:

1. Nationalism and Imperialism: These dictators aimed to revive their nations' past glory and expand their influence in line with imperialistic ideologies prevalent at the time. Hitler, for instance, sought to establish a greater Germany by reclaiming territories lost after World War 1 and expanding into neighboring countries.

2. Military Strength: The dictators believed in the superiority of their military forces, hoping that their highly trained and technologically advanced armies would easily overpower any resistance. Germany, in particular, had developed advanced military technologies and innovative warfare strategies, giving Hitler confidence in his ability to conquer Europe.

3. Weakness of Opposition: In the years leading up to World War 2, many European countries faced economic hardships, political instability, and internal conflicts. These weakened states provided an opportunity for dictators to exploit divisions and assert dominance. Additionally, fears of another major war and a desire to avoid conflict led some nations to pursue policies of appeasement, which further emboldened the dictators.

4. Ideological Pseudo-Justifications: Hitler, Mussolini, and the Japanese fascists propagated ideologies that portrayed their nations as superior, while dehumanizing and vilifying certain ethnic or cultural groups. These ideologies, combined with propaganda and indoctrination, fostered a sense of national unity and convinced their populations that they were on a righteous mission to conquer and dominate other nations.

It's important to note that these dictators' delusions of grandeur and their miscalculations of the strength and determination of their adversaries ultimately contributed to their downfall. Nonetheless, understanding their motivations and the political climate of that time helps us comprehend why they believed they could take over Europe and other places.
