The map of Europe which has Nato coloured in is very different to the one from a few decades ago. It appears to show a relentless Nato advance, right up to the Russian border. That shouldn't be a problem, as Nato is ostensibly a defensive bloc, though he sees that "advance" as a provocation and as a broken promise (he'll see what he wants to see and he hasn't got people around him to tell him otherwise). A wise agreement between Nato and Putin would involve keeping each other's weaponry well away from their borders. And not pointing missiles at each other. And somebody needs to tell him that Ukraine will not be joining Nato either in his or in Biden's lifetime. We're dealing with a bloke who doesn't need much of a pretext and who has an evangelical desire to restore the Russian empire. We've made the big mistake of failing to sufficiently recognise that.
