world war i ended in 1918, but the treaty of versailles left many issues unresolved and in 1939, world war ii began. in a brief essay, describe the major causes of world war ii, and explain how the response of the league of nations and of britain, france, and other european nations to axis aggression contributed to the start of the war?

I am not going to write the complete essay but I will give you a clear and simple explanation :)

So, when looking at the United Nations we know that they were very mad and furious at Germany and Germany's allies for WWI. Due to this, it gave many harsh and cruel punishments which left many countries regretting this decision. This decision angered Germany and it turned against the whole world, which brings up Hitler. He was so mad that they lost the war that he decided to start WWII in order to try and get even with everyone else. 

Hope This Helped!
