While I agree with the need to shut off Nordstream I, I am not sure Germany can afford this right now due to historically low gas reserves [2].
I have to disagree with the tone of the statement "We can afford the consequences". Who is "we"? The lower middle class of Germany, who already suffers some of the highest taxes in the world and the highest energy prices in the world? The government clearly does not care about energy prices: Gas prices are nearly 50% taxed, are they willing to lower it for lower income families? No.
