By that logic, countries like the US, UK, France, etc. shouldn't be allowed to have a standing military.
And yet, compared to every military in the past, compared to the fact that war was seen as a normal thing in the past, compared to how it used to be standard to rape and pillage in the past, and that was just expected and fine and normal, current modern militaries of the West are exceptionally disciplined, and their use by politicians doubly so.
Of course, that doesn't mean we can't do better and shouldn't.
But we do need to compare "How things have been for all of human history" to "How we do things now", and see that our modern democracies show immense restraint and a lack of malfeasance, compared to how they've been used in the past.
I feel that people view how the world is today, through such a restricted world view. Where the history of how things were, and the immense and great and incredible progress we've made, is thrown aside because "Oh bad thing happened!", and therefore "The entire West is completely corrupt and everything sucks and we should rip it all down because it's bad".
One only need take a tour around the rest of the world. To compare our militaries to those in non-democratic nations. To how those leaders act, in reality, compared to our leaders. Even the current US admin looks good, comparatively. And yes, I know that's saying a lot.
Nearly there...
Now ask yourself which government is currently bombing another country over one man's ego (or due to blackmail by an "ally"), and whether they're on that list, and whether the literal thousands of people killed are just acceptable sacrifices to maintain someone's worldview about 'the good guys'?
