OK Thomas, I'll bite. I'm in a bad mood today anyway, so what the hell.
All those people who joined the forces (certainly UK, US, all non-conscripting NATO countries) did so in order to defend democracy. Their right to freedom. That's what they signed up for, voluntarily. They may have had personal agendas (learn to fly/drive/fix things/cook(!)/stack blankets), but they all signed up for the overriding prinicple of defence.
And yes, some people probably did join with bloodlust in mind. But I'll guarantee you that either they changed their mind by the end of training, or didnt make the end of training.
I see you live in Vienna. Bit of a mixed bag of history there. Everything from Imperialism through Nazism, Communist uprisings, neutrality to democracy.
Good luck on here trying to attack our ethos anyway. You'll need it.
