WHAT IS THE AUMF?
AUMF is the acronym for Authorization for the Use of Military Force. The specific AUMF that Congress will debate will provide the legal authorization for the U.S. military to fight ISIS.
HOW DO YOU PRONOUNCE IT?
WHY DO YOU NEED AN AUMF?
WHY DO YOU NEED AN AUMF AGAINST ISIS?
Since the start of the airstrike campaign against ISIS, the Obama administration has relied on the AUMF’s from 2001 and 2002 as the legal justification for its airstrikes against ISIS.
WHAT IS IN THE OBAMA ADMINISTRATION’S PROPOSED AUMF?
For months there has been bipartisan congressional support for an ISIS-specific AUMF. However, some key members of Congress have wanted the Obama administration to take the lead in proposing what should be in a new AUMF.
The AUMF proposed by the Obama administration contains several main points. It would authorize military operations against ISIS for three years, allow for the limited use of ground troops by not authorizing "enduring offensive ground combat operations." It would also repeal the 2002 AUMF that authorized the ground invasion in Iraq, and provide reports every six months on the pace of operations.
AREN’T THERE ALREADY US TROOPS IN IRAQ?
WHY FOR ONLY THREE YEARS?
The proposed AUMF would last only three years. U.S. military officials have projected that the fight against ISIS could take several years, a minimum of three years. This is how long it would take to retrain the Iraqi military so it can defeat ISIS in Iraq as well as train a force of Syrian moderate opposition fighters who could take the fight to ISIS in Syria.
But there is also a political component too as there has been congressional and administration criticism that the 2001 AUMF was too open-ended. Renewing the AUMF three years from now would allow a public debate on how much longer the fight against ISIS should last.
WHAT HAS BEEN THE EARLY REACTION ON CAPITOL HILL? President Obama’s request is being met with early resistance on Capitol Hill, with critical questions and deep concern from Democrats and Republicans alike. No surprise, given the fierce partisan divide and the hangover of more than a decade of war. Sen. Tim Kaine of Virginia and other Democrats say they are troubled by the “breadth and vagueness” of the language involving ground troops. Kaine and others believe there is too much room for mission creep and say they would not support the proposal as it is now. Sen. John McCain and other Republicans say the president’s proposal has the opposite problem: It constricts the commander-in-chief’s flexibility. McCain, Sen. Lindsey Graham and others say they would not support the proposal as it is now. At issue is the interpretation of these five words, which would be prohibited in the AUMF: “enduring offensive ground combat operations.”
HOW LONG WILL THE CONGRESSIONAL DEBATE LAST? It will certainly last weeks, but could stretch into months.
SO, WHAT’S THE BOTTOM LINE – WILL THE AUMF PASS OR FAIL? It’s far too early to suggest the authorization will fail. But if it does, the White House has a backup plan: The proposal only seeks to repeal the 2002 AUMF, the original one passed by Congress in 2001 targeting Al Qaeda is still in place and is the basis for the fight already underway against ISIS.
