America First does not mean America paralyzed. The President, as Commander in Chief, possesses long-recognized authority to conduct limited military actions, especially when deterrence or immediate national security interests are involved. That authority has been exercised by Democrats and Republicans alike for decades, often with Congress responding afterward through funding or targeted authorizations.
The latest round of fighting between Pakistan and Taliban-run Afghanistan marks the most serious escalation between the two neighbors since the U.S. withdrawal.
