Russian invasion of Ukraine

That's a really interesting summary.

I don't think commentators are saying the problem came from NATO expansion as such. I think everyone acknowledges that the problem is Putin.

But if you're offering a balanced view then you've got to explain the strategic importance to Russia of the ex-USSR countries bordering Russia's warm water ports, Putin's view of the historical ties, and what the potential risk of a Western military force on your boarder is. Not to mention the internal political risk of a EU member, West-facing Ukraine being successful and prosperous.
