We live in a time of a true cultural revolution in Europe. The Polish and the German finance ministers can now finish each others' sentences.

Viewed from a German perspective, the old partner across the Rhine has been sputtering. This is especially true with regard to fiscal consolidation and reducing the overwhelming role of the state in its economy, as well as strengthening small and medium-size businesses. France has fallen behind not just Germany, but many of its other European peers on key issues.

It is as if the relocation of the German capital from Bonn, right on the Rhine, to far-away Berlin has made the French more removed from keeping up with the Germans.

Despite all the recent talk about the Franco-German relationship as the EU’s backbone, and all the related nervous talk about the emergence of a two-speed Europe, the trouble is that the latter is precisely what is now emerging between Berlin and Paris. The recent summit gave the impression that the Franco-German pair was very much in joint control. But it was not really the relationship of two equal partners, as Mr. Sarkozy often found himself uncomfortably on the defensive.

That is not the result of any German leadership desires, but simply a reflection of economic and financial performance — and hence competence. As a matter of fact, on that score, it is two other countries, Poland and Sweden, which are the ones the Germans truly respect. In the new Europe, alliances are — thankfully — built on performance and competence, not tradition and habit.

We can now truly speak of something heretofore unimaginable: a Polish-German axis.

As it stands, Europe's core of stability has simply been shifting slightly both northward and eastward. The main new co-dynamo is Poland.

One could be tempted to believe the side of the country in which the German capital is located has some magical effect on the economic performance of its respective large neighbor. France did well with Bonn nearby — and poorly with Berlin. In the case of Poland, it's the other way around.

The Poles have been very impressive in the way in which they have managed their economy over most of the past two decades. Under Prime Minister Tusk, the country is well-positioned to strengthen its position in core Europe even further.

The Poles have done so well that one can say that we live in a time of a true cultural revolution in Europe. What else should one call a situation where the Polish and the German finance ministers can now finish each others' sentences?

As France wobbles economically, which could throw Europe off-kilter, it is Poland that stands firm. France down, Poland up: The core holds.

But even when viewed in a broader framework, anybody with even the faintest sense of European history must cherish this moment. At long last, the word "axis" can be liberated from its dark historic connotations. We can now truly speak of something heretofore unimaginable: a Polish-German axis.

With that in mind, one has to wonder about a major diplomatic blunder in the French-German way of managing the eurozone crisis. It would not have taken much imagination to invite Polish Prime Minister Donald Tusk to those Franco-German summits in Deauville and Paris, unnecessarily deemed secretive, and involved him in the discussions and the presentation of the results.

Not only does Poland currently hold the EU presidency, which provides a formal reason. But what action could have better blunted the silly talk of a Franco-German condominium deciding over the heads of the other Europeans than to have Mr. Tusk there as a partner?
