Yeah, I note that the video isn't making that claim though. The video isn't saying "don't have a military" or "don't fight back" or even "don't fight wars". It's saying war sucks and there is no way to avoid it sucking, so it's never a solution, just sometimes a necessity.They do make perfectly reasonable points... but miss a whole lot of ones less related to very "here and now" of recent media narratives instead of considering the issue in full.
You can embrace the ideas proposed by even most reasonable pacifists all you want as your country. But in no way, shape or form it will guarantee that you will avoid war. If anything, its the opposite.
The Romans had the other half of the equation. Si vis pacem, para bellum.
Just because you don't want war, doesn't mean no one else will, and if you are unprepared for war, mentally or materially, that only makes those who think of it want war with you more, in expectation of a relatively easy victory. As the current case of Russia, or slightly earlier ISIL show, even trade and prosperity coming from peace only go so far, when not all cultures are as materialistic as current western one, and as such are perfectly willing to start wars despite the massive trade sanctions that it will result in. That's where the dreams of pacifists die. Other societies that disagree with them, oh the irony. Brought down to the same level as all the other ideas for a perfect world.
Personally, I'd go almost never. Vietnam's invasion of Cambodia is the one exception that sticks out to me of a war that made the world better than before the war, and even then it was initially defensive.
And this is what a libertarian is generally on the side of.Pacifists are the stepping stones of more martial societies on the road to empire. The only form of pacifism I have the remotest respect for is armed neutrality, the NAP given teeth (essentially militaristic liberals). As I understand it, that ideology is built around the term "don't step on me, or I will kill you."
Also, I'm not sure if you are from Europe, but a liberal isn't a libertarian in the US. A European liberal is more similar to US libertarians than US liberals (who are more like a British Labour party).
