The security regionalization of Europe is not a good sign for the future of the eurozone. A monetary union cannot be grafted onto security disunion, especially if the solution to the eurozone crisis becomes more integration. Warsaw is not going to give Berlin veto power over its budget spending if the two are not in agreement over what constitutes a security threat. This argument may seem simple, and it is cogent precisely because it is. Taxation is one of the most basic forms of state sovereignty, and one does not share it with countries that do not share one’s political, economic and security fate.
This goes for any country, not just Poland. If the solution to the eurozone crisis is greater integration, then the interests of the integrating states have to be closely aligned on more than just economic matters. The U.S. example from the late 18th century is particularly instructive, as one could make a cogent argument that American states had more divergent economic interests than European states do today, and yet their security concerns brought them together. In fact, the moment the external threat diminished in the mid-19th century due to Europe’s exhaustion from the Napoleonic Wars, American unity was shaken by the Civil War. America’s economic and cultural bifurcation, which existed even during the Revolutionary War, erupted in conflagration the moment the external threat was removed.
The bottom line is that Europeans have to agree on more than just a 3 percent budget-deficit threshold as the foundation for closer integration. Control over budgets goes to the very heart of sovereignty, and European nations will not give up that control unless they know their security and political interests will be taken seriously by their neighbors.
