The pacifist streak in German politics is a problem. But Greens and Social Democrats have to ask themselves: In an imperfect world, what do they prefer? The rise of the right or the success of the European project?

I do not think the British want to become America's "Airstrip One," as the British Isles are called in George Orwell's "1984." The EU's internal market was a massive success even before the UK joined it, and it joined because there was no real alternative. So while British tabloids are expecting to be punished by Germany, Brexit is punishment in itself.

If there ever was a time for a cool, rational and unemotional series of responses on the part of people in Europe, it is now. One reason is that Russia's President Vladimir Putin and Trump are very similar: They are macho types, they are bullies - and they want the same thing: to weaken the EU, albeit for different reasons. Trump, for his part, is a protectionist of the first order, and he wants to make his vision work. He shows no interest in competition with others, but aims to go back to the 1930s.

The largest weight is now on Germany's shoulders. Chancellor Merkel must continue to convince people of the EU's importance; she must spearhead the effort to redefine the EU. In order to do this, Germany must become a muscular democracy. It needs to shoulder far more responsibility for the physical security of Europe, especially Eastern Europe and the Mediterranean. So far, unfortunately, Germany has taken the lead in disrespecting Europe's borders by opening its doors to more than a million refugees and migrants.

Germany must continue to champion the world's biggest free single market, and under its leadership, the EU can overcome its internal differences.

You won't find anyone in the UK who doesn't admire what Germany has become. The bilateral relationship between London and Berlin will become more important in the future, and the UK government wants Germany to grow stronger - for Europe's sake. It is in Britain's national interest that the EU succeeds, and Prime Minster Theresa May knows this.
