Nationalism hasn't created 60 years of peace in Europe, it has created two world wars. Not that I expect some jingoist militaristic right-winger who lives in an anti-intellectual, post-factual world to understand this.
Bad trolling attempt by the way. Unlike you I am not a nationalist who gets wet pants when hearing the name of the nation he lives in due to the accident of birth so you cannot insult or provoke me via saying something bad about it. Revealed your lack of empathy, your lack of ability to think about how or what another guy thinks. It is not a weak word by the way, any good general (to bring in your favourite topic of wars, guns and soldiers) has to be empathic, has to be able to think like the enemy thinks.
