I think that support for Ukraine's effort to defend itself is legitimate. If it is, of course, it has to be carefully scaled, so that it actually improves their situation and doesn't escalate the conflict, to lead to destruction of Ukraine and possibly beyond sanctions against the aggressor, or appropriate just as sanctions against Washington would have been appropriate when it invaded Iraq, or Afghanistan, or many other cases. [...] However, I still think it's not quite the right question. The right question is: What is the best thing to do to save Ukraine from a grim fate, from further destruction? And that's to move towards a negotiated settlement.
