In short, the ground was well prepared for last Tuesday’s meeting. When Hollande arrived in Berlin on Tuesday evening, Merkel was all bonhomie.

No one should underestimate her smiles, her gestures, and her ability to make her guests feel genuinely welcome.

When Hollande, flanked by Merkel, inspected the guard of honor, during a brief respite from the rain which had already drenched him back in Paris during his post-inauguration parade, Merkel chaperoned him very nicely. She guided him, with the slightest of pushes, to turn the corner of the red carpet and continue with the inspection. Then, a few seconds later, she gestured to him that they should bow together. After that, it was marching orders, with some guidance, to end the ceremony.

Then it was down to dinner, and business, in the Chancellery.

Both leaders know exactly how deep their differences over the euro crisis run: Berlin still believes in austerity measures to balance the books. Paris believes a dose of Keynesianism to be a necessary palliative.

But at the short press conference after their dinner both agreed they were looking forward to working with each other anyway.

Actually, the history of Franco-German relations shows that leaders from the opposite political parties get on far better that those of similar ideological inclination.

Helmut Kohl, a conservative, managed to establish a close relationship with Francois Mitterrand, a socialist. It was even closer between Gerhard Schroder, a Social Democrat and Jacques Chirac.

In contrast, Merkel failed to have any empathy with Chirac. And it took her a long time – and all the pressure of the euro crisis – to develop any kind of a relationship with Sarkozy.

But they never seemed to share that sense of historical necessity to use the special Franco-German relationship for European ends.

Hollande, a sober, calm, persistent man whose character suits Merkel far better than his predecessor did, might just produce that spark that is needed to modernize the Franco-German relationship in a way that will strengthen Europe.

The fact that he has chosen Jean-Marc Ayrault, a former German professor and Germanophile as his prime minister seems very promising.

Let’s hope that they will not forget the wider issues of foreign policy.

Of course, both leaders know they have to tackle the euro crisis. Both leaders also have their electorates to satisfy. Don’t forget that Merkel faces re-election in 2013 so she might be a bit preoccupied.

Nevertheless, Hollande and Merkel will have to also find some time to work out the kind of relationship Europe wants with Russia, Ukraine, and Belarus, not to mention Turkey, the Middle East, and China.

These relationships are too important to be kept to the bilateral and national interest level. Europe has to think strategically about them. The future of the continent depends on that.

This means that once Hollande settles into the Elysee, his foreign policy advisors must be given rein to engage Germany and the rest of Europe in drawing up a new Security Strategy. The euro crisis is important, but France and Germany cannot continue to hide behind. It is time to develop a new foreign and security policy.
