as Russia sends more and more units to Ukraine’s borders, a grim momentum is building. Last week’s diplomacy yielded nothing. Some of Vladimir Putin’s demands are impossible for nato to accept, as he well knew. (Essentially, he wants nato never to admit new members, and to remove its forces from any country Russia threatens.) On January 19th President Joe Biden said that he expects Russia to “move in” on Ukraine. The first world war became inevitable once mobilisation orders had been issued in Berlin, argued A.J.P. Taylor, a British historian. Will NAto Attack Russia if it attack Ukraine ?
