Depends. The isolationists want to get rid of the IMF and World Bank no matter what. Don't you prefer to reform them as institutions which actually serve basic human needs?Isolationists also oppose the UN, the Int'l Criminal Court, and other multilateral institutions. Internationalists at least feel some sense of responsibility for the rest of the world, even if some/many of them are occasionally/sometimes/frequently wrong (depending on the politician and issue in question).BTW, if you check the Yahoo discussion board on Otto Reich's recent comments on Guatemala, you'll find that several Guatemalans concur that the US should mind its own business. I'd say the US has a historic responsibility to be engaged, since we can't turn back the clock to 1953 and prevent the USG from keeping out in the first place.
