One can make a good case that Britain's guarantee to Poland in 1939 was done badly. Britain failed to convince Hitler that she was serious, and that invasion of Poland would lead to war.
We can agree that the 'blame' falls on Hitler. But one can also reflect on whether Britain's actions could have been better thought out, and maybe learn some lessons for the future.
In the case of Putin's Russia, NATO is dealing with a major nuclear power. Saying that Putin is at fault is fine. I very much dislike Putin. But we have to co-exist with Russia whether we like it or not. I am interested in reading some 'realpolitik' on this topic. In particular, I'd like to understand Putin's and Russia's motives, fears, ambitions, etc.
edit: I just realised this is the same Putin apologist who has a whole list of articles blaming people other than Putin for this invasion.

Yes, he sounds like an unbiased source. Pretending to be anti-war when he's apparently just pro-Putin.
