In Ukraine the situation was already jittery enough. Donald Trump has been inventing ceasefires and buying Russian diesel to shore up his flagging popularity, while a sinister new wave of faster, jet-powered drones are breaking through Kyiv’s stretched air defences. Casualties are rising as the weather turns.
