Key Takeaways from the New National Defense Strategy

The U.S. Department of Defense has released its 2026 National Defense Strategy, prompting analysis from several experts. One takeaway is that the document is highly political and may signal a "spheres of influence" approach to foreign policy, which could affect deterrence. The strategy also places a central focus on the Western Hemisphere, designating the Arctic and Panama Canal as key terrain. Additionally, it names "narco-terrorists" as a key threat, implying continued U.S. activity against narco-states in the Americas.
