I need help plz. How did conflicts in Europe and Asia in the first half of the 20th century lead to an expansion of America’s role in the world?

uhh i forgot.sorry my dudes

As countries were taking over countries the United States wanted to help to preserve democracy.  It started by providing resources to allied countries to eventually join the war ourselves.

julius caesar turned the roman republic into the roman empire by coming in and taking the "dictator" role during the time of a civil war (elites vs lower classes) winning battles and reputation, then declaring him dictator for life

hope this : )

yes they have. but is this a true false question? if it is, the answer is true.
