For the first time since the second world war, Russia has been invaded. On the previous occasion the Red Army’s Ukrainian troops helped beat back the Nazi assault in Russia’s Kursk province. Now it is Ukrainians who are advancing over the same ground. Ukraine’s surprise attack, which began on August 6th, is bold and daring, and could change the narrative of the war. It is also a gamble which could go badly wrong.
