One of the most important of executive powers is the president's role as [[Powers of the president of the United States#Commander-in-chief|commander-in-chief]] of the [[United States Armed Forces]]. The power to declare war is constitutionally vested in Congress, but the president has ultimate responsibility for the direction and disposition of the military. The exact degree of authority that the Constitution grants to the president as commander-in-chief has been the subject of much debate throughout history, with Congress at various times granting the president wide authority and at others attempting to restrict that authority.<ref>{{Cite web |url=https://constitutioncenter.org/interactive-constitution/articles/article-ii/commander-in-chief-clause-ramsey-and-vladeck/clause/25 |title=Common Interpretation: Commander in Chief Clause |last=Ramsey |first=Michael |last2=Vladeck |first2=Stephen |website=National Constitution Center Educational Resources (some internal navigation required) |publisher=National Constitution Center |access-date=May 23, 2017}}</ref> The framers of the Constitution took care to limit the president's powers regarding the military; [[Alexander Hamilton]] explained this in [[Federalist No. 69]]:{{quote|The President is to be commander-in-chief of the army and navy of the United States.{{nbsp}}...

Lo poder de declarar la guèrra es balhat al Congrè, mas lo President ten la darrièra responsabilitat de la direcciion e provesiment del militari. Lo gra exacte de l’autoritat que la constitucion garantís al president coma comandant en cap faguèt l’objècte de fòrça debats dins l’istòria, amb lo Congrès qu’a vegadas garantís la mai granda autoritat al president e a d’autras assajan de restrénher aquela autoritat. Los redactor de la Constitucion prenon garda a limitar los poder militaris del president.
A l’epòca modèrna, en conformitat del <nowiki><i>War Powers Resolution</i></nowiki>, Lo Congrès deu autorizar quin que siá desplegament de la tropas passant 60 jorns, quitament se los mecanismes de desencadenament jamai foguèron utilizats, fasent la resolucion ineficaça. Mai, lo Congrès ten un ròtle de verificacion del poder militari presidencial pel contraròtle de las despensas e la reglamentacion militara. Los Presidents dins l’istòria inicièt lo procediment de decaracion de la guèrra, mas las criticas remarquèron que per diferents confictes foguèron pas declarats per una declaracion oficiala del President, coma [[Theodore Roosevelt]] agissent militarament al [[Panamà (país)|Panamà]] en 1903,la [[Guèrra de Corèa]], la [[Guèrra de Vietnam]], e las invasions de [[Grenada]] en 1983 e [[Panamà (país)|Panamà]] in 1989.
