Executive Order 14167 represents a systematic expansion of executive power over border security, consolidating military authority under the guise of national emergency. While the order cites constitutional duties, it bypasses legislative oversight and constitutional safeguards like the Posse Comitatus Act, institutionalizing military dominance over civilian functions. The lack of democratic deliberation and legal constraints risks normalizing authoritarian governance patterns, with historical parallels to 20th-century executive overreach. The most concerning aspect is the permanent assignment of military missions to border security, which erodes institutional checks and threatens the separation of powers.
