To what extent did the two world wars settle the issues that caused them

The two world wards settled the issues that caused them through imperialism and this was made possible in two stages: WW I wound up the four resident European Empires - German, Austro-Hungarian, Czarist Russian & Turkish Othman Empires. WW II wound up the eight overseas Empires - British, French, Dutch, Belgian, Italian, Portuguese, Spanish & Danish. Hope this answers your question.
