To get a good answer to your question, you should tell us what the problems are supposed to have arisen from. Various problems arose from various things and helped lead to WWII.
For example, problems arose from the Treaty of Versailles that ended WWI. That treaty punished Germany very harshly for WWI. The punishments (including taking away parts of Germany's territory and prohibiting them from having much in the way of armed forces) made Germans very angry. Their anger over their treatment helped allow Hitler to come to power and led to WWI.
At the same time, there were problems in Asia that helped lead to WWII. Japan did not have much of an empire in Asia and they felt they needed and deserved one. They did not like the idea that the European countries were allowed to have empires while they (Japan) were told not to have one. When Japan tried to take an empire anyway, they came in conflict with European countries and the US. That helped lead to WWII.
There are other problems that led to WWII, but these are the major ones.
