The Value of EURO-SOF
The 2026 U.S. National Defense Strategy re‑prioritizes global threats, positioning U.S. Special Operations Forces (SOF) in Europe as a critical deterrent against Russia and emerging challenges from China, Iran and North Korea. SOF’s value proposition hinges on deterrence by denial—maintaining positional advantage—and deterrence by cost imposition—imposing unacceptable losses on an adversary. By achieving domain awareness and coherence, SOF integrates air, land, sea, cyber and space capabilities with NATO partners, creating a multi‑domain force multiplier. This posture not only safeguards the U.S. homeland but also fuels innovation that feeds the broader defense industrial base.
