The Monroe Doctrine was an American Foreign Policy still in effect
today. It stated that the US would not allow foreign powers to come and
interfere in the politics and lives of North, Central, and South
Americans. If a foreign power attempted to do so then the US would stop
them. By force if necessary. </span>

Robust knowledge is knowledge that has stood the test of time and survived constant criticism. When a piece of knowledge is examined for its truthfulness, critics make a consensus over whether it's correct or not. The knowledge becomes robust if a consensus is reached on its truthfulness and if it survives criticism from different sides and angles. This is difficult to apply to history because those who make history usually have a different perception of what happened. What was an assassination in the mind of one country, is a move of fighting for freedom in another country. That's why a consensus needs to be made on a global scale regarding historical developments and it is done through the academia where people write papers and critics from all over the world critique them to eventually reach an idea of truthful global history.
The major causes for the start and development of the World War II are the expansionism, nationalism, and natural resources.
This war was started because of the territorial appetites of some countries, namely Germany, Italy, and Japan, each them having their own vision and primary goal. Germany wanted to take over all the historic territories where the Germanic people lived, Italy wanted to resurrect the Roman Empire, while Japan wanted to get hold onto parts of Asia that were rich in natural resources as they have very few.
The nationalism led to mass murders on ethnic basis, with Germany and Japan being the biggest contributors to that, killing all the people that they considered as lesser human being or not suitable.
The natural resources were also one of the main reasons. Germany was trying to get to multiple places that were rich in natural resources, especially with oil, which is why the Soviets were attacked, so that Germany can get its hands on Azerbaijan. Japan too wanted and managed to conquer territories that were rich in oil and metals, as well as other natural resources, providing them with basis for further expansion and strengthening.
