German industry says a complete shutoff of Russian gas to Germany would be catastrophic. Paul Krugman, an expert on international economics, looks at it in this NYT report. He says estimates show a worst case scenario drop of 2.1% in GDP for Germany to shutoff Russian supplies of energy. This estimate is from ECONtribute a thinktank from the Universities of Bonn and Cologne. This reluctance says Krugman to take the tough decisions such as turning off Russian energy supplies prolongs the war in Ukraine and its painful consequences in food scarcity and inflation all over Africa, Asia and Latin America. By comparison Greece, Ireland, Spain and Portugal went through severe downturns as a result of debt crises and economies that were mismanaged, with 27% loss of GDP in Greece, says Krugman. 

Merkel's government argued for strict austerity policy during the eurozone financial crisis. By comparison says Krugman the shutoff of Russian energy supplies only imposes 2.1% loss in GDP that the German economy could handle.This estimate is also similar to estimates by Bruegel Institute and International Energy Agency, says Krugman. It would also speed up climate change action in Germany and set an example for Europe. German Economy minister Habeck's plan on alternative sources of renewable energy goes part of the way to accomplish this yet more needs to be done to correct the errors of policies from the Merkel administration that allowed German dependence on Russian energy to reach 55%.

It is hard to comprehend why the Merkel administration could not be uneasy with something that would give Russia a huge leverage over the German economy and limit its voice in world affairs. It is now left to chancellor Scholz to correct the errors of the Merkel administration and of past members of his party the SPD, such as Mr. Steinmeier and the Schroeder SPD administration that preceded Merkel. Difficult questions have to be shouldered by the Christian Democrats and the Social Democrats. It is only through the courage shown by Annalena Baerbock of the Greens Party, in laying bare what these German policies were leading to, that Germany is recovering her voice in the world. In his speech to parliament making a U turn from the old policies Scholz credited Annalena Baerbock for the hard work in convincing Germans of the need for action.
