No matter how much Canadian and EU trade officials worked to bring Wallonia on board, all attempts have so far failed. Unless Magnette, now joined by the government in the Belgian region of Brussels, lifts his opposition to CETA, the damage to Europe will be irreparable.

For one thing, other countries outside Europe will ask whether it is really worth trying to reach a trade agreement with the EU if it cannot even strike a deal with an open, liberal, democratic country such as Canada. These bitter disagreements over ratifying CETA bode ill for the EU and the United States, which are concluding talks on the proposed Transatlantic Trade and Investment Partnership (TTIP). And if anyone hoped to believe that it would be easy for Britain to reach a trade deal with the EU after it leaves the bloc, such hopes are now dashed.

Even more worryingly for Europe’s ambitions to be a truly global player, the CETA negotiations have shown that the EU is now beholden to groups of politicians and an ever-growing movement that opposes globalization and free trade.

Forget the fact that it was trade, combined with huge financial support from the United States, that helped Europe get back onto its feet after World War II. Forget the fact that a 2011 EU trade deal with South Korea has already led to an increase in EU service exports to South Korea of 40 percent and a rise in goods exports of 55 percent. Such statistics simply get in the way or are ignored by some politicians in Europe, who believe that such trade deals only benefit multinational companies.

Antiglobalizers, who are grouped around populists and Euroskeptic movements, would do well to visit small, export-driven companies in Germany. These companies support CETA and TTIP. If TTIP were ever concluded—and it is now increasingly unlikely—then those small and medium-sized German companies that export to the United States would not have to change the colors and configurations of wires in electric plugs to conform to U.S. standards. The savings would run into hundreds of millions of euros according to the Federation of German Industries. But that, it seems, is an irrelevant detail for antiglobalizers.

Leaving all these issues aside, and regardless of what happens to CETA, this latest setback for the EU reveals two important facts.

The first is that the European Commission, which under the EU treaties has the power to negotiate trade agreements, has had its authority undermined. Under pressure from national governments, the commission put forward CETA as a so-called mixed agreement, having previously emphasized that it saw the deal as an EU-only agreement.

It has been impossible to square that circle. A mixed agreement has to be ratified not only by the EU as a whole but also by the 28 member states. In the case of Belgium, that means regional parliaments such as that of Wallonia must give their consent as well. An EU-only agreement, by contrast, gives the EU alone the power to conclude the deal.

Some regional legislatures have seized on the growing movement against free trade, leaving the commission unable to defend its powers, as the case of CETA shows. The result is that EU trade policy now risks going in the same direction as foreign policy: renationalization. But if some member states believe they can go it alone in the twenty-first century, they are living a dangerous delusion.

This is why the second fact revealed by CETA—whether or not Wallonia will change its mind—is that there is a glaring need for a two-speed Europe. The eurozone countries cannot afford to ignore the implications of Brexit and the rejection of CETA. Both events weaken Europe and the euro. And even though the public mood is against more integration, the eurozone countries still have sufficient authority to pull the EU out of its miserable and dangerous malaise by pushing for a two-speed Europe. It is that move that could keep the political and economic integration project alive.

As it is, the failure of CETA has shown how the decisionmaking process in the EU is inexorably leading the bloc toward paralysis and implosion. Just when the Western liberal order is being challenged not only by Russia and China but also by politicians and movements in the West, it is time for eurozone leaders to rescue Europe, before it is too late.
