Kurt Volker, former envoy for Ukraine of the US administration, said: “We have known for some time that the Russians had undermined the Kakhovka dam, to be ready to detonate it, if they deem it useful. They waited so far, as they hoped to regain the lost territories in the Kherson area. The fact that they have decided to blow it up shows that they have given up on the idea of being able to retake those regions.”
