Sen. Rand Paul introduced S.J. Res. 46 (SJ46), a constitutional declaration of war against the Islamic State (ISIS). If passed, it would be the first constitutionally-declared foreign conflict that the U.S. government has been engaged in since World War II.

โ€œI believe the President must come to Congress to begin a war and that Congress has a duty to act. Right now, this war is illegal until Congress acts pursuant to the Constitution and authorizes it,โ€œ Sen. Paul said.

Constitutionally-speaking, Paul couldnโ€™t be more right.

The Founders expresslyย prohibited the Executive branch from having the power to unilaterally determine whether or not the country would engage in war. Few were more adamant about this than James Madison, the โ€œFather of the Constitution,โ€ who wrote the following text that Paul included in (SJ46):

โ€œThe constitution supposes, what the history of all governments demonstrates, that the executive is the branch of power most interested in war, and most prone to it. It has accordingly with studied care vested the question of war in the legislature.โ€

Thomas Jefferson supported this viewย quite eloquently when, in 1801, he said that, as President, he was โ€œunauthorized by the Constitution, without the sanction of Congress, to go beyond the line of defense.โ€

Thus, Congress has the power to determine ifย the country will wage offensive war and against whom.ย  Once that decision is made by the Congress, the President is in charge of waging that war.

WORD GAMES

Confronted with the Constitutional requirement that Congress is the federal branch that determines when the country goes to war, supporters of unilateral executive power will often take one of two paths to avoid following the Constitutional mandate that Congress declare the war before the Executive can take action.

1. Refer to the action as defensive.

This is the classic argument that โ€œproves too much.โ€ As James Madison pointed out, a constitutional argument is โ€œtriable by its consequences.โ€ Here, the consequences would be essentially unlimited executive warย power, since almost any significant activity can be linked to โ€œnational securityโ€ or a need to โ€œdefend American interests.โ€ Because it is incontrovertible that unlimited executive warย power is not what the Foundersโ€™ Constitution granted, the argument fails.

The argument is also a scary one, because historically โ€œnational securityโ€ often has been used to excuse the suspension of individual rights.

In short, actions only qualify as โ€œdefensiveโ€ under the constitution if they are in response to a direct attack or an imminent threat of attack. While not conclusive, there is Founding-eraย evidence to support the constitutionality of a defensive military response toย protect U.S. personnel abroad as well. Itโ€™s also instructive to note that even this broader understanding is limited to โ€œU.S. personnel abroadโ€ and not merely โ€œU.S. interests.โ€

2. Refer to the action as something other than โ€œwar.โ€

Under the Constitution, a war is a war whether you call it a war or something else.

Constitutional scholar, Rob Natelson, wrote about the legal meaning of the word โ€œwarโ€ย in March, 2011:

Founding-Era dictionaries and other sources, both legal and lay, tell us that when the Constitution was approved, โ€œwarโ€ consisted ofย anyย hostilities initiated by a sovereign over opposition.ย  A very typical dictionary definition was, โ€œthe exercise of violence under sovereign command against such as oppose.โ€ย  (Barlow, 1772-73).ย  I have found no suggestion in any contemporaneous source that operations of the kind the U.S. is conducting were anything but โ€œwar.โ€ [emphasis added]

All U.S. military actions qualify as โ€œviolence under sovereign command.โ€ And attacks, whether for strategic, political, or humanitarian purposes, are always โ€œover opposition.โ€

NARROW IN FOCUS

There are many reasons why following the Constitution is not only within the law, but a good idea too.

The first goal of having Congress declare war was to ensure that the representatives of the states and the people would be the ones discussing matters of peace and war.

A Congressional declaration of war limits Presidential powers, narrows the focus of the action, and implies, or clearly stipulates a precise end-point to the conflict. When left in the hands of just one person, we can be assured that there is only one opinion on war. Conversely, the more people there are involved in making that decision, the greater the chance that the country will not get involved in costly, deadly and worthless wars.

Paulโ€™s resolution follows this path by repealing previously-broad laws and putting forward a narrow declaration moving forward:

(a) Declaration.โ€”The state of war between the United States and the organization referring to itself as the Islamic State, also known as the Islamic State of Iraq and the Levant (ISIL) and the Islamic State of Iraq and Syria (ISIS), which has been thrust upon the United States, is hereby formally declared pursuant to Article I, section 8, clause 11, of the United States Constitution.

(b) Authorization.โ€”The President is hereby authorized and directed to use the Armed Forces of the United States to protect the people and facilities of the United States in Iraq and Syria against the threats posed thereto by the organization referring to itself as the Islamic State, also known as the Islamic State of Iraq and the Levant (ISIL) and the Islamic State of Iraq and Syria (ISIS).

While this particular policy measure may be the right path forward or the wrong path forward โ€“ the bigger issue at hand isย whether or not Congress will actually follow the constitution. Sen. Paulโ€™s effort to bring the Constitution to the forefront is laudable, even though itโ€™s almost certain that Congressย will, as they have for over 70 years, refuse to follow the constitution and will continue to allow the President to do what he wants.
