Marvel at the heroism and resilience of Ukraine. In the first days of war, the armoured might of Vladimir Putin shrivelled before the courage of the nation he had attacked. In the face of Mr Putin’s invasion, the Ukrainian people have discovered they are ready to die for the idea that they should choose their own destiny. To a cynical dictator that must be incomprehensible. To the rest of humanity it is an inspiration.
If only this week’s bravery were enough to bring the fighting to an end. Alas, Russia’s president will not withdraw so easily. From the start, Mr Putin has made clear that this is a war of escalation—a hygienic word for a dirty and potentially catastrophic reality. At its most brutal, escalation means that, whatever the world does, Mr Putin threatens to be more violent and more destructive even, he growls, if that means resorting to a nuclear weapon. And so he insists that the world back off while he sharpens his knife and sets about his slaughter.
