**UNITED STATES CONSTITUTION – ARTICLE I, SECTION 8, CLAUSE 11**
**“The Congress shall have Power … To *declare* War …”**
BRIEF FOR THE PROPOSITION THAT ONLY CONGRESS MAY INITIATE HOSTILITIES
I. Question Presented
Whether, under the original meaning of the U.S. Constitution, the President possesses any Article II authority to employ military force abroad when the United States, its forces, or its property are **not** under actual or imminent attack.
II. Summary of Argument
The Declare-War Clause assigns *exclusive* authority to initiate hostilities to Congress. At the 1787 Convention the Framers deliberately replaced the verb “make” with “declare” to ensure the Executive could *repel* invasions but never *commence* war. Founding-era commentary—Federalist No. 69, Madison’s writings, and Jefferson’s correspondence—confirms this allocation. Early practice (Quasi-War, Barbary Wars) underscores that Presidents sought statutory approval even for limited engagements. Modern scholarship over the last four decades (Glennon, Fisher, D’Errico, Finucane, Zeisberg) reaches the same conclusion: apart from repelling sudden attacks or rescuing citizens in immediate peril, unilateral presidential uses of force are unconstitutional. The War Powers Resolution of 1973 codifies this boundary.
III. Constitutional and Statutory Provisions Involved
1. U.S. **Const. art. I, § 8, cl. 11** (Declare-War Clause).
2. U.S. **Const. art. II, § 2, cl. 1** (Commander-in-Chief Clause).
3. **War Powers Resolution**, 87 Stat. 555 (1973). ([avalon.law.yale.edu][1])
IV. Statement of Facts (Historical Background)
* 17 Aug 1787: Madison and Gerry move to substitute “declare” for “make” war to prevent the Executive “from *commencing* war” while preserving authority to “repel sudden attacks.” The motion carries 8-1. ([avalon.law.yale.edu][2])
* The finished Constitution divides war powers: Congress declares; the President commands forces once war is authorized.
* In the 1798 Quasi-War and the 1801 Barbary conflict, Presidents Adams and Jefferson waited for express statutory authorization before initiating offensive operations—evidence of the early understanding.
V. Argument
A. The Text, Structure, and Drafting History Foreclose Unilateral Presidential War-Making
1. **Textual allocation.** Article I grants Congress the power “to declare War,” while Article II merely designates the President commander-in-chief. The pairing was meant to mimic Britain’s division between King and Parliament in reverse—legislature initiates, executive executes. Hamilton: “The President is to be commander-in-chief … but … *the power of declaring war is fully and exclusively vested in the legislature.*” ([avalon.law.yale.edu][3])
2. **Convention debate.** The explicit change from “make” to “declare” was, in Madison’s words, to deny the Executive “the whole of the war-making power.” Delegates uniformly affirmed only a defensive capacity for the President. ([avalon.law.yale.edu][2])
B. Early Practice Mirrors the Original Understanding
* **1798–1800 Quasi-War with France:** Congress enacted limited force statutes; Adams did not strike first on his own.
* **1801–1805 Barbary Wars:** Jefferson sought authorization for hostilities against Tripoli.
These episodes show that even “limited” or maritime actions were considered to require legislative approval. See Fisher, *Presidential War Power* (2d ed. 2004). ([amazon.com][4], [kansaspress.ku.edu][5])
C. Article II Confers Only Defensive Power Absent Congressional Authorization
Modern scholarship synthesizing Founding sources reaches consensus: the President may act *solely* to repel sudden attacks.
* **Jonathan D’Errico**, *The Specter of a Generalissimo: The Original Understanding of the President’s Defensive War Powers*, 42 Fordham Int’l L.J. 153 (2018) (executive power limited to defense). ([ir.lawnet.fordham.edu][6])
* **Michael J. Glennon**, *The Constitution and Chapter VII of the U.N. Charter*, 85 Am. J. Int’l L. 74 (1991) (no Article II authority for offensive action). ([opus.us.edu.pl][7])
* **J. Finucane**, *Presidential War Powers, the Take Care Clause …*, 106 Cornell L. Rev. 2020 (limited strikes constitute “war” requiring Congress). ([cornelllawreview.org][8])
D. The War Powers Resolution Codifies and Reinforces the Original Allocation
Congress may tolerate only a 60-day emergency use of force when “a national emergency is created by attack upon the United States, its territories or its armed forces.” § 2(a)(1)–(3). Any other initiation of hostilities is unlawful without prior authorization. ([avalon.law.yale.edu][1])
E. Counter-Arguments and Rebuttal
* **“Presidential Quick-Strike” theory.** Proponents rely on post-WWII precedents (e.g., Kosovo 1999, Syria 2018) and claim such actions are below the constitutional threshold of war. **Rebuttal:** The Framers used “declare” broadly to cover *any* initiation of force; no distinction exists between “big” and “small” wars. Founding debates offered one—and only one—unilateral power: *repelling* attacks. ([constitution.congress.gov][9], [yalelawjournal.org][10])
VI. Conclusion
The original meaning, early practice, and modern academic consensus all point to a single constitutional rule: **Except when repelling an actual or imminent attack, the President lacks authority to initiate hostilities abroad without prior congressional authorization.** Limited or “surgical” strikes fall within Congress’s exclusive power “to declare War.”
