I would say that authoritarianism is prevented in this case.
Authoritarianism means that there is only one person deciding what is right or what is wrong, according to their own thoughts and ideas. Nobody else has a say in a such an organization. However, here, that is obviously not the case, which is why that is prevented when a lot of people express their own opinions.
Your question is not specific but I will give you some insight on World War II that may help you answer this question:
There 2 events that are most mentioned which triggered World War II. The first would be the Marco Polo Bridge Incident between China and Japan on July 7, 1937.
Another historical even that has been mentioned to have started WWII was invasion of Germany in Poland in September 1, 1939. Because of this France and Britain declared war on the Nazi's.
To pay debts, specifically war debts
Durning the wars Britain used a lot of money mainly on weaponry and such, to pay its debt they taxed the people.
