Putin is banking on a failure of political will in the west before Russia runs out of firepower | Timothy Garton Ash

Democratic leaders need to prepare their citizens for a long struggle over Ukraine - and a hard winter

The Russo-Ukrainian war is coming down to a race between the weakening political will of western democracies and the deteriorating military means of Vladimir Putin's dictatorship. But this race will be a marathon, not a sprint. Sustaining that political will requires the kind of farsighted leadership which most democracies are missing. It calls for a recognition that our own countries are also, in some important sense, at war - and a corresponding politics of the long haul.

Is this what you hear when you turn on your television in the United States (where I am now), Germany, Italy, Britain or France? Is this a leading topic in the Conservative party contest to decide Britain's next prime minister, or the run-up to the Italian election on 25 September, or the campaign for the US midterm elections on 8 November? No, no and no. We are at war," I heard someone say recently on the radio; but he was an energy analyst, not a politician.
