While it is true US foreign policy favored isolationism pre-WWII, calling current restrictions on immigration into the US "isolationist" is a conflation of the term. The US maintains a global military presence and there is no evidence this will change until another state actor (or a coalition of state actors) forcibly shrinks the US global footprint. In George Friedman's book, "The Next 100 Years" the central theme to current US foreign policy is that, as a global super power, the US will actively seek to destabilize regions of the world that threaten its interests now and in the future. That simple guideline can help to understand the lionshare of American foreign policy decisions post WWII and is of course, not an isolationist policy whatsoever. Edit: spelling of Friedman
