Libertarians often run into the problem of simplifying their views when it comes to foreign policy with the non-aggression principle. While the principle works, and it is (or at least should be) the basis for almost everything when it comes to libertarians, when used in the context of current international relations, a libertarian looks ignorant and uneducated about the subject. This was brought into light when Gary Johnson was asked in 2016 about his thoughts on Aleppo.
As libertarians, or just fans of non-intervention, we should still study the issues and being able to discuss them with people we disagree with. Many limited government folks love libertarianism when it comes to the free market, low (or no) income taxes, and keeping government out of people’s lives, but when it comes to foreign policy, they all of a sudden shy away.
We’re at a point where having a level head about what’s going on around the world is more important than ever. Israel and Iran look like they’re about to start a war, which would only throw the Middle East into more chaos. Russia and America would almost certainly be drawn into battle. Who else might get involved? Saudi Arabia? China? Who knows?! This could be the start of WWIII!
