Not by choice, Russians still think the collapse of USSR a tragic mistake, and Putin’s rhetoric ties directly back to it.
Russian “defence” spending is skyrocketing, Russia is holding frequent manoeuvres righ in NATO borders, keeps flying bombers ever-so-slightly into NATO country airspace’s... and most of all, Russia shows it is more than happy to apply brute force to achieve political goals. In Ukraine, Georgia, who’s next?
Denmark, Poland and Sweden, not to mention the Baltic states, are rightly concerned about Russia’s posturing. If it’s not meant to be intimidating and creating a low-level Cold War, then it’s a very odd way of showing neighbourly love.
I’m sure comparisons to American imperialism will follow, and maybe justifiably so. But crucially, US does not invade European countries, voila the pertinent difference.
