I think that’s the point. I’m old enough to remember Bush and Blair wanting UN support for Iraq but ditched the idea when they wouldn’t get it. And young enough that my parent’s generation have never seen a war and so don’t remember why the UN was created in the first place. We live in dangerous times with very poor leaders and politics
Ya just don’t buy EU or UK would start ww3. There are much smarter and better economics and influence strategies to play out that are much less bloody to its own population.
