NATO Shield Act

(a) Findings. Congress finds that:

(1) The North Atlantic Treaty Organization constitutes a cornerstone of United States national security and collective defense.

(2) The North Atlantic Treaty Organization creates binding mutual defense obligations that directly affect the likelihood and scope of armed conflict involving the United States.

(3) Withdrawal from such a treaty would substantially alter United States exposure to hostilities, deterrence posture, and global military commitments.

(4) Under article I of the Constitution, Congress retains authority to declare war and to regulate and govern the Armed Forces.

(5) The War Powers Resolution reflects Congress intent to ensure collective judgment in decisions that may lead to hostilities.

(b) Purpose. The purpose of this Act is to clarify that withdrawal from a mutual defense treaty constitutes a decision with direct war powers implications requiring congressional participation.
