What are the 3 main causes of world war 2?
The main causes of World War II are two in number and may be
described briefly as follows. First, unresolved conflicts from
World War I led to the renewal of rivalries between leading
European nations, principally Germany in opposition to Britain and
France, with war nearly inevitable as a result. Second, the
powerful ambitions of Hitler and his fellow Nazis sought domination
of the continent, and these ambitions were not checked (or snuffed
out) by western nations when Nazi Germany was its weakness -- thus
leading indirectly to large-scale war years later.
