I made it through the airport crush to Berlin at the beginning of last week to see how Germany is faring under Olaf Scholz, Angela Merkel’s tough-minded centre-left successor. Under Merkel, Germany was important because it was the key to EU decision-making, but towards the end of her chancellorship, the country slowed down, there was too little change and, as we now know, Merkel misjudged Vladimir Putin’s revanchist ambitions and thirst for personal glory.
