....yeah, and non-isolationist libertarians everywhere. Many of the founders (Paine, Washington, Jefferson & Monroe) were isolationists (or non-interventionists if it'll get you to quit whining). And during their time, I agree with their stances. Today you can't be an isolationist on Enewetak Atoll or Antarctica.
You don't get to whine about "pejoratives," and then call somebody else a whiner when they call you on your hypocrisy.
The simple fact is that noninterventionism is the only libertarian foreign policy, and that runs the spectrum from minarchist to anarchist. In other words, there are no libertarians who aren't noninterventionists.
Don't confuse non-interventionism with never doing anything. It's more of a stance in which we take no proactive measures, unlike the way we have been behaving recently with wars such as Korea, Vietnam, Iraq, et al. This country has needlessly been at war for nearly the entirety of time since WWII. The need for our action in both world wars is inarguable, and I highly doubt you will find many libertarians who would argue we shouldn't have intervened; However with that being said we shouldn't intervene with countries for our own personal gain (e.g. Iran, Cuba, Guatemala, et al). There is an undeniable need to stay vigilant, but no need whatsoever to remain aggressive.
