Vanquishing the Principle of Unanimity in E.U. Foreign Policy: On the Impact of Oil

There nothing like a sudden dramatic spike in the price of oil in Europe from a war in Iran to prompt E.U. leaders to make speeches as if hell is freezing over and drastic action is urgently needed in terms of federal rather than piecemeal-state foreign policy. Behind President Von der Leyen’s call for the E.U. to do more in foreign policy was her point that the union could no longer afford the principle of unanimity in the European Council in foreign policy. The Iran War had raised the price not only of oil, but also of the unanimity requirement in the Council not only in foreign policy, but also defense. With 27 states at the time and an increasingly belligerent international context, including military aggression against Ukraine, Gaza, and Iran, the E.U. could not rely on a world order regulated by international law. The spike in gas prices, even more than Russia’s invasion of Ukraine, brought this point close to home.

As the U.S. began its military attacks in Iran, “European benchmark gas prices jumped 80% in two days while brent crude edged closer to 84 dollars a barrel.”[1] When oil prices surpassed €87 ($100) per barrel roughly a week into the war, Viktor Orbán of the E.U. state of Hungary “called on the European Union to suspend sanctions on Russian energy imports.”[2] Never mind that Russia’s 4 year-old unimpeded invasion of Ukraine was a threat on the E.U.’s eastern border; restoring cheaper gas prices was more important, at least to Hungary. The E.U.’s geopolitical interests do not reduce to a state’s economic interests, however, and so President Von der Leyen spoke on the need for a more active E.U. foreign policy.

It was not the first time that the president had warned that the traditional world order was “rapidly crumbling under mounting violations of international law.”[3] In her speech, she said, “Europe can no longer be a custodian for the old-world order, for a world that has gone and will not return.”[4] There had been too many cases of breaches of international law with impunity as the UN and the International Criminal Court stood by utterly impotent. E.U.’s foreign minister, Kaja Kallas “pointed the finger at Russia’s decision to launch the full-scale invasion of Ukraine . . . as the cataclysm that precipitated the ‘erosion of international law’ . . . and enabled the return of what she described as ‘coercive power politics.”[5] In her speech, Kallas said, “That (invasion) did not go unnoticed. Instead, it sent a signal around the world that there is no more accountability for one’s actions: the rulebook has been thrown out of the window.”[6] Netanyahu’s government in Israel could unleash a holocaustic genocide in Gaza with a presumption of impunity, and Trump’s government in the U.S. could forcibly remove the president of Venezuela and kill Iran’s highest figure without fear of being held accountable by the U.N. or the International Criminal Court. Militaristic aggression was gaining a foothold in the world as international organizations stood by in utter impotence. The very notion of law at the international level could be surmised to be a misnomer.

Finally, E.U. officials were feeling a sense of urgency from war abroad because the sudden spike in oil and gas prices in Europe from Trump’s military attacks in Iran could not be ignored. Kallas stressing “that a rules-based international order is vital to avoid the inevitable anarchy” was no longer enough.[7] “Von der Leyen added another key priority on which the EU should focus to reinforce its geopolitical clout: its internal decision-making rules.”[8] Problematically, the E.U.’s foreign policy was bound by the principle of unanimity in the European Council and the Council of the E.U. such that “the 27 member states must agree on a common line of action before moving forward.”[9] So it only took the E.U. state of Hungary to veto the $91 billion loan for Ukraine, and the E.U. was stymied in coming up with a foreign policy on Trump’s military attacks against Iran because of differences between the states. Alternatively, going by qualified-majority voting would have enabled a consensus (i.e., short of unanimous consent) that could have become the E.U.’s foreign policy, which would have been much stronger in the world than were the various positions of the 27 state governments.

The relationship is clear between calls for a rules-based international order “with teeth” and a stronger decision-making rule in the European Council in foreign policy (and defense): a more active E.U. in foreign policy (and defense) was necessary due to the increased militaristic aggression abroad because the latter could have a very significant detrimental economic affect in Europe. Political pressure was thus building for the E.U.’s 27 state governments to finally relinquish their veto-power in foreign policy (and defense). Power is not relinquished easily, so not even higher oil and gas prices could be enough pressure for the states to agree to apply qualified-majority voting to foreign policy (and defense).

The mechanism called “enhanced cooperation,” which I contend elsewhere is a misnomer for what is really increased federal authority for at least nine states but not all of them, could be a means to bring qualified majority voting to the E.U.’s foreign policy that would cover only those states that have agreed to relinquish their veto power in that domain. I suspect that eventually, all of the E.U. states would be included, so “enhanced cooperation” can be understood as a temporary device that gets around the conflict of interest facing the state governments in their decisions on whether to allow the E.U. to become more active in foreign policy (and defense) than the principle of unanimity would permit.
