Attorney General Eric Holder recently addressed Northwestern University’s School of Law and used that opportunity to address the legality of targeted killings, one of President Obama’s most recent additions to his counterterrorism toolbox. The case surrounding the controversy of the speech is the killing of US-born Anwar al Awlaki, a radical cleric closely associated with al Qaeda and implicated in terror plots and attacks against the United States, in a drone strike in September 2011. The airstrikes that targeted Awlaki’s convoy in Yemen are nothing new in the war on terror, but this situation was different in that the target was a US citizen.
Other than citing a 2001 joint Congressional resolution dubbed “The Authorization for Use of Military Force,” Holder failed to give any real legal basis for his reasoning, offering only political rhetoric to explain the Obama administration’s decision to take out one of America’s most wanted terrorists.
Our legal authority is not limited to the battlefields in Afghanistan. Indeed, neither Congress nor our federal courts has limited the geographic scope of our ability to use force to the current conflict in Afghanistan. We are at war with a stateless enemy, prone to shifting operations from country to country. Over the last three years alone, al Qaeda and its associates have directed several attacks – fortunately, unsuccessful – against us from countries other than Afghanistan. Our government has both a responsibility and a right to protect this nation and its people from such threats.
This does not mean that we can use military force whenever or wherever we want. International legal principles, including respect for another nation’s sovereignty, constrain our ability to act unilaterally. But the use of force in foreign territory would be consistent with these international legal principles if conducted, for example, with the consent of the nation involved – or after a determination that the nation is unable or unwilling to deal effectively with a threat to the United States.
Furthermore, it is entirely lawful – under both United States law and applicable law of war principles – to target specific senior operational leaders of al Qaeda and associated forces. This is not a novel concept. In fact, during World War II, the United States tracked the plane flying Admiral Isoroku Yamamoto – the commander of Japanese forces in the attack on Pearl Harbor and the Battle of Midway – and shot it down specifically because he was on board. As I explained to the Senate Judiciary Committee following the operation that killed Osama bin Laden, the same rules apply today.
Now, it is an unfortunate but undeniable fact that some of the threats we face come from a small number of United States citizens who have decided to commit violent attacks against their own country from abroad. Based on generations-old legal principles and Supreme Court decisions handed down during World War II, as well as during this current conflict, it’s clear that United States citizenship alone does not make such individuals immune from being targeted [emphasis added]. But it does mean that the government must take into account all relevant constitutional considerations with respect to United States citizens – even those who are leading efforts to kill innocent Americans. Of these, the most relevant is the Fifth Amendment’s Due Process Clause, which says that the government may not deprive a citizen of his or her life without due process of law.
Let me be clear: an operation using lethal force in a foreign country, targeted against a U.S. citizen who is a senior operational leader of al Qaeda or associated forces, and who is actively engaged in planning to kill Americans, would be lawful at least in the following circumstances: First, the U.S. government has determined, after a thorough and careful review, that the individual poses an imminent threat of violent attack against the United States; second, capture is not feasible; and third, the operation would be conducted in a manner consistent with applicable law of war principles.
The evaluation of whether an individual presents an “imminent threat” incorporates considerations of the relevant window of opportunity to act, the possible harm that missing the window would cause to civilians, and the likelihood of heading off future disastrous attacks against the United States. As we learned on 9/11, al Qaeda has demonstrated the ability to strike with little or no notice – and to cause devastating casualties. Its leaders are continually planning attacks against the United States, and they do not behave like a traditional military – wearing uniforms, carrying arms openly, or massing forces in preparation for an attack. Given these facts, the Constitution does not require the President to delay action until some theoretical end- stage of planning – when the precise time, place, and manner of an attack become clear. Such a requirement would create an unacceptably high risk that our efforts would fail, and that Americans would be killed.
Whether the capture of a U.S. citizen terrorist is feasible is a fact-specific, and potentially time-sensitive, question. It may depend on, among other things, whether capture can be accomplished in the window of time available to prevent an attack and without undue risk to civilians or to U.S. personnel. Given the nature of how terrorists act and where they tend to hide, it may not always be feasible to capture a United States citizen terrorist who presents an imminent threat of violent attack. In that case, our government has the clear authority to defend the United States with lethal force.
Of course, any such use of lethal force by the United States will comply with the four fundamental law of war principles governing the use of force. The principle of necessity requires that the target have definite military value. The principle of distinction requires that only lawful targets – such as combatants, civilians directly participating in hostilities, and military objectives – may be targeted intentionally. Under the principle of proportionality, the anticipated collateral damage must not be excessive in relation to the anticipated military advantage. Finally, the principle of humanity requires us to use weapons that will not inflict unnecessary suffering.
