United States–Canada Military Partnership

No two nations share a deeper or more integrated military alliance than the United States and Canada. From joint air defense under NORAD to seamless cross-border military operations, the U.S.-Canada security partnership is unique in its level of coordination, interoperability, and trust. As Arctic security, cyber threats, and great-power competition reshape global defense priorities, the binational command structure and combined military forces of these two nations remain a pillar of North American and global stability.
