acting like american imperialism and strict isolationism are the only alternatives is a false dichotomy. if by 'overall success' you mean strengthening american hegemony in the world to the benefit of its ruling class, i'd certainly agree (even though one could make valid arguments about how a less militaristic and more mutually beneficial approach could have been more successful in doing so) - but to characterise america's net influence on the world since ww2 as 'undoubtedly positive' requires some insanely thick, neocon-tinted glasses, and has to be a uniquely jingoistic perspective.
america has committed (and facilitated) unspeakable crimes and violations of international law in those decades, to a degree that not a single other country has in that period. in that regard, they have proven themselves 'worthy' successors to the british empire.
I say isolationist because I don't know a more appropriate word. What I mean is an America content to let other powers dominate their regions at the detriment of our own country, those countries, and the world as a whole. It would be an America that lets the Chinese and Soviet backed North take South Korea, lets Saddam take Kuwait, lets nations in the Middle East invade other nations without American forces going in, lets Iran harass tankers in the seas without military retaliation, etc etc.
Our security guarantees and presence in many countries acts to ensure peace and prosperity. Without that traditional American policy, the world would be in a much darker place. We shouldn't take for granted how peaceful and prosperous the world has been post-WW2, and that doesn't mean we can't criticize American foreign policy when it missteps(like in Iraq).
