|Europe's economic crisis has helped far-right politicians, such as Geert Wilders, gain support [GALLO/GETTY]
As if the economic ramifications of a full-blown Greek default were not terrifying enough, the political consequences could be far worse. A chaotic eurozone breakup would cause irreparable damage to the European integration project, the central pillar of Europe's political stability since World War II. It would destabilise not only the highly indebted European periphery, but also core countries such as France and Germany, which have been the architects of the project.
The nightmare scenario would also be a 1930s-style victory for political extremism. Fascism, Nazism, and communism were children of a backlash against globalisation that had been building since the end of the nineteenth century, feeding on the anxieties of groups that felt disenfranchised and threatened by expanding market forces and cosmopolitan elites.
Free trade and the gold standard had required downplaying domestic priorities such as social reform, nation-building and cultural reassertion. Economic crisis and the failure of international cooperation undermined not only globalisation, but also the elites that upheld the existing order.
As my Harvard colleague Jeff Frieden has written, this paved the path for two distinct forms of extremism. Faced with the choice between equity and economic integration, communists chose radical social reform and economic self-sufficiency. Faced with the choice between national assertion and globalism, fascists, Nazis, and nationalists chose nation-building.
Fortunately, fascism, communism and other forms of dictatorships are passé today. But similar tensions between economic integration and local politics have long been simmering. Europe's single market has taken shape much faster than Europe's political community has; economic integration has leaped ahead of political integration.
End of the EU?
The result is that mounting concerns about the erosion of economic security, social stability and cultural identity could not be handled through mainstream political channels. National political structures became too constrained to offer effective remedies, while European institutions still remain too weak to command allegiance.
It is the extreme right that has benefited most from the centrists' failure. In Finland, the heretofore unknown True Finn party capitalised on the resentment around eurozone bailouts to finish a close third in April's general election. In the Netherlands, Geert Wilders' Party for Freedom wields enough power to play kingmaker; without its support, the minority liberal government would collapse. In France, the National Front, which finished second in the 2002 presidential election, has been revitalised under Marine Le Pen.
"When I am president, in a few months' time, the eurozone probably won't exist."
- Marine Le Pen
Nor is the backlash confined to eurozone members. Elsewhere in Scandinavia, the Sweden Democrats, a party with neo-Nazi roots, entered parliament last year with nearly six per cent of the popular vote. In Britain, one recent poll indicated that as many as two-thirds of Conservatives want Britain to leave the European Union.
Political movements of the extreme right have traditionally fed on anti-immigration sentiment. But the Greek, Irish, Portuguese and other bailouts, together with the euro's troubles, have given them fresh ammunition. Their Euro-scepticism certainly appears to be vindicated by events. When Marine Le Pen was recently asked if she would unilaterally withdraw from the euro, she replied confidently: "When I am president, in a few months' time, the eurozone probably won't exist."
As in the 1930s, the failure of international cooperation has compounded centrist politicians' inability to respond adequately to their domestic constituents' economic, social and cultural demands. The European project and the eurozone have set the terms of debate to such an extent that, with the eurozone in tatters, these elites' legitimacy will receive an even more serious blow.
'Less bad' options
Europe's centrist politicians have committed themselves to a strategy of "more Europe" that is too rapid to ease local anxieties, yet not rapid enough to create a real Europe-wide political community. They have stuck for far too long to an intermediate path that is unstable and beset by tensions. By holding on to a vision of Europe that has proven unviable, Europe's centrist elites are endangering the idea of a unified Europe itself.
Economically, the least bad option is to ensure that the inevitable defaults and departures from the eurozone are carried out in as orderly and coordinated a fashion as possible. Politically, too, a similar reality check is needed. What the current crisis demands is an explicit reorientation away from external financial obligations and austerity to domestic preoccupations and aspirations. Just as healthy domestic economies are the best guarantor of an open world economy, healthy domestic polities are the best guarantor of a stable international order.
The challenge is to develop a new political narrative emphasising national interests and values without overtones of nativism and xenophobia. If centrist elites do not prove themselves up to the task, those of the far right will gladly fill the vacuum, minus the moderation.
That is why outgoing Greek Prime Minister George Papandreou had the right idea with his aborted call for a referendum. That move was a belated attempt to recognise the primacy of domestic politics, even if investors viewed it, in the words of a Financial Times editor, as "playing with fire". Scrapping the referendum simply postpones the day of reckoning and raises the ultimate costs to be paid by Greece's new leadership.
Today, the question is no longer whether politics will become more populist and less internationalist; it is whether the consequences of that shift can be managed without turning ugly. In Europe's politics, as in its economics, it seems there are no good options - only less bad ones.
