The E.U. and U.S. on Defense and Foreign Policy: Helping Ukraine

In March, 2025 after the U.S. had direct talks with Russia on ending Russia’s invasion of Ukraine, the E.U. stepped up its game in helping Ukraine militarily. This was also in the context of a trade war between the E.U. and U.S., which did not make transatlantic relations any better. The E.U.’s increasing emphasis on military aid to Ukraine and the related publicity inadvertently showcased how federalism could be applied to defense and foreign policy differently that it has in the U.S., wherein the member states are excluded, since the Articles of Confederation, when the member states were sovereign within the U.S. confederation. Although both manifestations of early-modern federalism have their respective benefits and risks, I contend that the E.U.’s application of federalism to the two governmental domains of power is more in the spirit of (dual-sovereignty) federalism, even though serious vulnerabilities can be identified.

Kaja Kallas, the E.U.’s foreign minister, “pitched an ambitious plan to mobilize up to to €40 billion in fresh military support for Ukraine, which, if achieved, would represent a twofold increase from the defence assistance the European Union provided” in 2024.[1] Whether premised on the assumption that Russia would not agree to a truce or that Ukraine would need additional leverage in negotiations, “the Kallas initiative” put the E.U.’s defense and foreign policy in the spotlight globally. Lest it be assumed by assuming an exact likeness to the U.S. federal system that the E.U.’s defense and foreign policy areas were exclusive competencies (i.e., domains of enumerated power) at the federal level, the E.U.’s state governments, including their respective foreign ministers, played a significant role in the actual provision to Ukraine of artillery ammunition, missiles, drones, and even fighter jets. This arrangement, which includes overall federal coordination and significant funding, resembles the directive, which is a federal law that requires the state governments enact legislation to implement the content of the federal law. That Kallas, the federal foreign minister, took “into account” non-lethal provisions, including “training and equipment for Ukrainian brigades, . . . to ensure the participation of neutral” state governments shows just how much of a role the E.U. states had at the time in defense and foreign policy.[2]

Marco Rubio, Kallas’ counterpart in the U.S., would not have even consulted with state governments in coming up with an initiative regarding Ukraine. That approach, wherein foreign policy and defense are completely federalized, does not reflect modern (i.e., dual-sovereignty) federalism, whereas the shared competencies of the E.U. do. This is not to say that every enumerated power or federal competency should be shared. In fact, that the principle of unanimity applied to foreign policy and defense in the E.U. represents a serious vulnerability. Essentially, the requirement that every state government consent treats modern (dual-sovereignty) federalism as if it were confederalism, where the states hold all governmental sovereignty. Similarly, David Cameron, a prime minister of the ex-E.U. state of Britain, confused the two in stating that the E.U. is just another international network.” Given this category mistake, the E.U. was better off after Britain seceded from the union. Even the linguistic subterfuge of “Brexit,” as well as Kallas’ strange job title as “high representative” rather than foreign minister, attests to the vulnerability inherent in obfuscating (early) modern federalism with confederalism.

In short, involving the state governments in foreign policy and defense federal policy and legislation applies federalism more so than does consolidating those two domains at the federal level, and yet giving each state government a veto not only renders the federal system vulnerable to being exploited and paralyzed from within, but also treats a federal system in which two systems of government each have some amount of sovereignty like a confederation in which the states retain sovereignty.

The U.S. could improve how it manifests federalism by having the heads of the state governments represent them in the U.S. Senate, just as the heads of the state governments in the E.U. sit in the European Council. Additionally, the U.S. member states could play more of a role in the implementation of foreign policies and defense, such as in receiving money from the Pentagon to send machinery from the states’ respective militaries (called militias) to countries that are to be supported militarily. The federal level could then act as a check on corruption in the implementation. To be sure, giving the state governments veto-power would carry the check-and-balance feature of federalism too far. So both the E.U. and U.S. could stand to improve their respective federal systems towards ever perfect union—neither one being a trading “bloc” or confederation.
