Reaction after World War II did not persist, but soon ran its course, and the necessities, real and perceived, of the United States’ role as world power and chief guarantor of the peace operated to expand the powers of the President and to diminish congressional powers in the foreign relations arena. President Truman did not seek congressional authorization before sending troops to Korea, and subsequent Presidents similarly acted on their own in putting troops into many foreign countries, including the Dominican Republic, Lebanon, Grenada, Panama, and the Persian Gulf, and most notably Indochina.183 Eventually, public opposition precipitated another constitutional debate whether the President had the authority to commit troops to foreign combat without the approval of Congress, a debate that went on inconclusively between Congress and Executive184 and one which the courts were content generally to consign to the exclusive consideration of those two bodies. The substance of the debate concerns many facets of the President’s powers and responsibilities, including his obligations to protect the lives and property of United States citizens abroad, to execute the treaty obligations of the Nation, to further the national security interests of the Nation, and to deal with aggression and threats of aggression as they confront him. Defying neat summarization, the considerations nevertheless merit at least an historical survey and an attempted categorization of the arguments.

The Historic Use of Force Abroad.—In 1912, the Department of State published a memorandum prepared by its Solicitor which set out to justify the Right to Protect Citizens in Foreign Countries by Landing Forces.185 In addition to the justification, the memorandum summarized 47 instances in which force had been used, in most of them without any congressional authorization. Twice revised and reissued, the memorandum was joined by a 1928 independent study and a 1945 work by a former government official in supporting conclusions that drifted away from the original justification of the use of United States forces abroad to the use of such forces at the discretion of the President and free from control by Congress.186

New lists and revised arguments were published to support the actions of President Truman in sending troops to Korea and of Presidents Kennedy and Johnson in sending troops first to Vietnam and then to Indochina generally,187 and new lists have been propounded.188 The great majority of the instances cited involved fights with pirates, landings of small naval contingents on barbarous or semibarbarous coasts to protect commerce, the dispatch of small bodies of troops to chase bandits across the Mexican border, and the like, and some incidents supposedly without authorization from Congress did in fact have underlying statutory or other legislative authorization. Some instances, e. g., President Polk’s use of troops to precipitate war with Mexico in 1846, President Grant’s attempt to annex the Dominican Republic, President McKinley’s dispatch of troops into China during the Boxer Rebellion, involved considerable exercises of presidential power, but in general purposes were limited and congressional authority was sought for the use of troops against a sovereign state or in such a way as to constitute war. The early years of this century saw the expansion in the Caribbean and Latin America both of the use of troops for the furthering of what was perceived to be our national interests and of the power of the President to deploy the military force of the United States without congressional authorization.189

The pre-war actions of Presidents Wilson and Franklin Roosevelt advanced in substantial degrees the fact of presidential initiative, although the theory did not begin to catch up with the fact until the “Great Debate” over the commitment of troops by the United States to Europe under the Atlantic Pact. While congressional authorization was obtained, that debate, the debate over the United Nations charter, and the debate over Article 5 of the North Atlantic Treaty of 1949, declaring that “armed attack” against one signatory was to be considered as “an attack” against all signatories, provided the occasion for the formulation of a theory of independent presidential power to use the armed forces in the national interest at his discretion.190 Thus, Secretary of State Acheson told Congress: “Not only has the President the authority to use the armed forces in carrying out the broad foreign policy of the United States implementing treaties, but it is equally clear that this authority may not be interfered with by the Congress in the exercise of powers which it has under the Constitution.”191

The Theory of Presidential Power.—The fullest expression of the presidential power proponents has been in defense of the course followed in Indochina. Thus, the Legal Adviser of the State Department, in a widely circulated document, contended: “Under the Constitution, the President, in addition to being Chief Executive, is Commander in Chief of the Army and Navy. He holds the prime responsibility for the conduct of United States foreign relations. These duties carry very broad powers, including the power to deploy American forces abroad and commit them to military operations when the President deems such action necessary to maintain the security and defense of the United States. . . .”

“In 1787 the world was a far larger place, and the framers probably had in mind attacks upon the United States. In the 20th century, the world has grown much smaller. An attack on a country far from our shores can impinge directly on the nation’s security. In the SEATO treaty, for example, it is formally declared that an armed attack against Viet Nam would endanger the peace and security of the United States.”

“Under our Constitution it is the President who must decide when an armed attack has occurred. He has also the constitutional responsibility for determining what measures of defense are required when the peace and safety of the United States are endangered. If he considers that deployment of U. S. forces to South Viet Nam is required, and that military measures against the source of Communist aggression in North Viet Nam are necessary, he is constitutionally empowered to take those measures.”192

Opponents of such expanded presidential powers have contended, however, that the authority to initiate war was not divided between the Executive and Congress but was vested exclusively in Congress. The President had the duty and the power to repeal sudden attacks and act in other emergencies, and in his role as Commander in Chief he was empowered to direct the armed forces for any purpose specified by Congress.193 Though Congress asserted itself in some respects, it never really managed to confront the President’s power with any sort of effective limitation, until recently.

The Power of Congress to Control the President’s Discretion.—Over the President’s veto, Congress enacted the War Powers Resolution,194 designed to redistribute the war powers between the President and Congress. Although ambiguous in some respects, the Resolution appears to define restrictively the President’s powers, to require him to report fully to Congress upon the introduction of troops into foreign areas, to specify a maximum time limitation on the engagement of hostilities absent affirmative congressional action, and to provide a means for Congress to require cessation of hostilities in advance of the time set.

The Resolution states that the President’s power to commit United States troops into hostilities, or into situations of imminent involvement in hostilities, is limited to instances of (1) a declaration of war, (2) a specific statutory authorization, or (3) a national emergency created by an attack on the United States, its territories or possessions, or its armed forces.195 In the absence of a declaration of war, a President must within 48 hours report to Congress whenever he introduces troops (1) into hostilities or situations of imminent hostilities, (2) into a foreign nation while equipped for combat, except in certain nonhostile situations, or (3) in numbers which substantially enlarge United States troops equipped for combat already located in a foreign nation.196 If the President introduces troops in the first of these three situations, then he must terminate the use of troops within 60 days after his report was submitted or was required to be submitted to Congress, unless Congress (1) has declared war, (2) has extended the period, or (3) is unable to meet as a result of an attack on the United States, but the period can be extended another 30 days by the President’s certification to Congress of unavoidable military necessity respecting the safety of the troops.197 Congress may through the passage of a concurrent resolution require the President to remove the troops sooner.198 The Resolution further states that no legislation, whether enacted prior to or subsequent to passage of the Resolution will be taken to empower the President to use troops abroad unless the legislation specifically does so and that no treaty may so empower the President unless it is supplemented by implementing legislation specifically addressed to the issue.199

Aside from its use as a rhetorical device, the War Powers Resolution has been of little worth in reordering presidential-congressional relations in the years since its enactment. All Presidents operating under it have expressly or implicitly considered it to be an unconstitutional infringement on presidential powers, and on each occasion of use abroad of United States troops the President in reporting to Congress has done so “consistent[ly] with” the reporting section but not pursuant to the provision.200 Upon the invasion of Kuwait by Iraqi troops in 1990, President Bush sought not congressional authorization but a United Nations Security Council resolution authorizing the use of force by member Nations. Only at the last moment did the President seek authorization from Congress, he and his officials contending that he had the power to act unilaterally.201 After intensive debate, Congress voted, 250 to 183 in the House of Representatives and 53 to 46 in the Senate, to authorize the President to use United States troops pursuant to the U. N. resolution and purporting to bring the act within the context of the War Powers Resolution.202

By contrast, President George W. Bush sought a resolution from Congress in 2002 to approve the eventual invasion of Iraq before seeking a U. N. Security Council resolution, all the while denying that express authorization from Congress, or for that matter, the U. N. Security Council, was necessary to renew hostilities in Iraq. Prior to adjourning for its midterm elections, Congress passed the Authorization for Use of Military Force against Iraq Resolution of 2002,203 which it styled as “specific statutory authorization within the meaning of section 5(b) of the War Powers Resolution.” On signing the measure, the President noted that he had sought “an additional resolution of support” from Congress, and expressed appreciation for receiving that support, but stated, “my request for it did not, and my signing this resolution does not, constitute any change in the long-standing positions of the executive branch on either the President’s constitutional authority to use force to deter, prevent, or respond to aggression or other threats to U. S. interests or on the constitutionality of the War Powers Resolution.”204 In the Bush administration’s view, the primary benefit of receiving authorization from Congress seems to have been the message of political unity it conveyed to the rest of the world rather than the fulfillment of any constitutional requirements.

Although there is recurrent talk within Congress and without as to amending the War Powers Resolution to strengthen it, no consensus has emerged, and there is little evidence that there exists within Congress the resolve to exercise the responsibility concomitant with strengthening it.205
