The incoming Trump administration has been supportive of this European initiative. It is consistent with the president-elect’s stated desire to disengage the United States from security matters on the continent, and instead have the European Union and the United Kingdom take the lead. But a deployment of European forces to Ukraine will inevitably entangle the Americans. European militaries depend on their U.S. allies for out-of-area operations. Inevitably, a large deployment to Ukraine will once again expose this dependency when they turn to the United States for help with critical tasks such as air lift, logistics, and intelligence that they cannot conduct alone.
