Why I am fighting to end the rubber stamp for war

From start to finish, our entire experience in Afghanistan underscores how deficient Congress has been in this arena.

On August 17, 1787, the delegates to the Constitutional Convention spent the final hours of the week embroiled in debate over how to start a war. The debate focused on the phrase “to make war,” and its placement within the powers of the Congress. Pierce Butler and Charles Pinckney of South Carolina spoke in opposition, noting the sluggish nature of convening Congress and its subsequent proceedings. Mr. Butler, in particular, favored placing the responsibility on the shoulders of the president, noting a president’s possession of “all the requisite qualities,” and restraint to “not make war but when the nation will support it.” 

Together, James Madison and Elbridge Gerry proposed a compromise, striking “make” in favor of “declare,” intentionally preserving a small window of latitude for a president to repel sudden attacks against the nation. The compromise succeeded on a vote of 8-1-1 with only New Hampshire opposed. Elbridge Gerry, evidently disturbed by the ease and confidence with which his fellow delegates proposed vesting such power in one office, said he “never expected to hear, in a republic, a motion to empower the Executive alone to declare war.”  

I have stood on the Senate floor as exasperated as Elbridge Gerry at the constant usurpation of the central role of Congress in matters of war by presidents of both political parties — and the recent blunder of President Biden’s withdrawal from Afghanistan provides tragic illustration of the consequences when executive power goes unchecked by the legislative branch. Our entire experience in Afghanistan, from start to finish, underscores the need for an active and engaged Congress in matters of war, while providing essential lessons for future U.S. conflicts.

First, in declaring war, Congress must clearly identify the enemy and provide defined objectives. In the wake of the devastating attacks of September 11, 2001, Congress passed the 2001 Authorization for the Use of Military Force (AUMF), recognizing the necessity of preventing Al Qaeda from launching further attacks on American soil. However, in the mid-2000s with Al Qaeda severely weakened, holding almost no footing in Afghanistan, the U.S. mission shifted to rebuilding Afghanistan physically and reshaping the country’s government in the image of the United States. Despite a 180-degree change in objective, Congress did not repeal, replace, or even amend the 2001 AUMF. The consequences? An additional 15 years of engagement, lives lost, tax dollars spent, and total discontinuity on the goal of our enduring presence.  

Second, while Congress alone is responsible for declaring war, the responsibility of the legislative branch does not end there. Congress cannot wash its hands of the failures of U.S. engagement and withdrawal in Afghanistan. Despite numerous oversight hearings, Special Inspector General Reports, and the bombshell Afghanistan Papers from the Washington Post, Congress allowed U.S. engagement in Afghanistan to continue far beyond what it authorized in the 2001 AUMF. Furthermore, it poured trillions of dollars into failing missions and programs without reform. Yet, Congress possessed the tools to address these challenges all along. Congress could have withheld funds, passed measures to address identified shortfalls in particular programs, and even amended the 2001 AUMF to require reauthorization of U.S. engagement. Despite these options, Congress remained idle. 

Finally, Congress, not the president, should decide when a war is over. From the first days of our nation through the Second World War, all wars declared by Congress ended with the ratification of a peace treaty by the U.S. Senate. As the nature of U.S. engagement in conflict abroad changed from the Cold War era onward, presidents’ goals for conflicts abroad became less clear. From the Truman Doctrine to the Global War on Terror, our goals, though noble, provided no identifiable end. One of the major revelations from the Afghanistan Papers was the lack of mission understanding by the majority of senior leaders running the operations. Presidents of both political parties in the modern age continuously fail to define a realistic vision of victory — perhaps because there is no debate when only one individual writes the script. Congress, in addition to providing a declaration and defined mission set for war, must play a role in disengaging the U.S. from conflict, especially when presidents prove incapable of “facilitating a peace.”

In Congress, a substantive debate on war powers is long-overdue, and U.S. engagement in Afghanistan over the last decade and the recent blundered U.S. withdrawal present an opportunity for Congress to act today in order to prevent similar mistakes tomorrow. I along with my colleagues Chris Murphy (D-CT) and Bernie Sanders (I-VT) introduced the National Security Powers Act earlier this year, which would restore Congress’ role in national security decision-making, primarily in the war-powers arena.

Despite political differences, as members of the branch of government most accountable to the people, we all feel the weight of American blood and treasure sacrificed in our nation’s wars. After years of failed engagement in Afghanistan, Congress can no longer serve as a rubber stamp on the sidelines. Never, in our republic, should a president wield exclusive power over our nation’s wars.
