A week ago, eight weeks before President-elect Trump is due to take over, President Biden approved the firing of US ballistic missiles deep into Russia. Two days ago, the first of those missiles was fired at the Russian city of Karachev, 130 kilometres from the Russia – Ukraine border.

Yesterday Biden agreed to provide Ukraine with anti-personnel landmines.

In what appears to have been a response, Russia/China/someone has cut undersea communication cables between Scandinavian countries and Eastern Europe.
