I think that one of the motivating factors that drove America to intervene in the affairs of another nation was the Cold War.  The American fear of Communism guided American foreign policy and also guided the basic idea of what America was going to do in the world.  It also drove America's place within it.  To this end, America sought to inject itself into other nations' affairs if there was a hint of Communist control at stake.  American intervention in South and Central America, South East Asia, and Africa was driven by the Cold War ideology that permeated American government for much of the second half of the 20th century.  The Central Intelligence Agency was commissioned with the duty of engineering and fomenting revolution or strengthening corrupt governments' control in other nations so long as it helped to prevent the rise of Communism in that country.  To this end, foreign relations and the intervention that might have come about in the second half of the last century was a construct of the Cold War belief system that was the paradigm for American foreign policy in stopping Communism at all costs.
