What I said, originally, is that it is neither naïve nor immoral nor unphilosophical to support a democracy that is being attacked by a dictatorship. On the contrary, it is the natural, logical, and moral thing to do. — Olivier5
And then your sole support for that assertion was the people you've met in some African nations prefer democracy. — Isaac
So far, the idea has not really been challenged much so I haven't provided additional arguments. But I can try to add a few arguments, if the topic is of interest.
Prior to any consideration of political regime, and the varied levels of freedom and security they afford to their citizens, to me the first and most important point here is that of aggression vs defence. There is no moral symmetry between an aggressor and his victim. Since 1945 and probably before, the principle of self-defense as a right, and the prohibition of wanton aggression extend beyond the individual, and also apply to those nations who signed the UN charter, including of course Russia and Ukraine.
These principles (that a UN charter signatory should not wage war on another; and that an aggressed signatory nation has a right to defending herself) are the cornerstone of our present world order. The prohibition of aggression suffers one exception: a war or a military operation can be approved by the UN security council (another cornerstone of the present world order).
These principles were of course disrespected by many nations since 1945, but only gravely undermined by a permanent member of the UN Security Council twice (to my math): by the US in Iraq war 2, and by Russia in Crimea and now in Ukraine mainland.
So yes, the US started it. Rest assured that I was just as opposed to the wanton aggression of Iraq by the US and UK as I am opposed to the wanton agression of Ukraine by Russia. For the exact same reason: it gravely undermined international law and the credibility of the present UN system, which maintains some level of peace building capacity.
(and yet Iraq was a dictatorship and the UK/US are sorts of democracies, because to me the prohibition of aggression trumps other principles -- I don't believe in exporting democracy at gunpoint)
Now this UN system may be highly imperfect, but it is a system at least trying to contribute to world peace. Without it, untill someone proposes something else, in the post UN world now concocted by Xi and Putin and whose recipe Bush wrote, what will deter a new wave of wars of plunder?
Nothing. There will be no rules whatsoever in international relations. Not even a pretense of one. Not even a hope of one.
So as someone attached to diplomacy and peace, I say I oppose wanton aggression. This is a moral stance based on the search for the common good. For world peace. For my kids' sake too.
Now you can laugh.
