S. 5623 — Reaffirming Extended Nuclear Deterrence Act of 2026

This section expresses the sense of Congress that the United States extended nuclear deterrent remains vital to national security, has prevented major-power conflict for more than seven decades, and should be sustained through modernization, allied consultations with the Republic of Korea, Japan, Australia, and NATO, and pursuit of verifiable arms control agreements. It states that such deterrence complements nonproliferation goals under the 1968 Nuclear Non-Proliferation Treaty and counters nuclear expansion by Russia, China, and North Korea.
