'Isolationist' is one of the buzz pejoratives that globalists use to denote someone who has what they perceive to be an opposite set of values from them. Isolationism was once a feature of the Left in America, when they wanted a 'more humble foreign policy' (to use a term used, ironically by George W. Bush before the war). Now, it is a synonym for 'racist' where it was once a synonym for 'pacifist'. The globalist version of a pacifist is going into another country and kindly reminding them that there's no freedom without forced freedom, usually in the form of democracy. Just an example of how certain terms can be given radically different ideological values over time.
