Now that I think about it, Rise to Globalism by Ambrose and Brinkley, and From Wealth to Power give a good sense or an actual explanation on why the US has gone from isolationist at the turn of the 20th century to “meddling” after WWII.

It seems obvious to me that the advent of technologically advanced weapons (including planes), the US’s financial position at the end of WWII, and its protective connection with Europe as a result of the Cold War, are the major indicator of its willingness to “jump in.” However, there is a bigger political issues; unfortunately, it seems to be more of a domestic than international problem.
