Earlier this week, we wrote about a significant but often overlooked aspect of the drone wars in Pakistan and Yemen: so-called signature strikes, in which the U.S. kills people whose identities aren’t confirmed. While President Obama and administration officials have framed the drone program as targeting particular members of Al Qaeda, attacks against unknown militants reportedly may account for the majority of strikes.
The government apparently calls such attacks signature strikes because the targets are identified based on intelligence “signatures” that suggest involvement in terror plots or militant activity.
So what signatures does the U.S. look for and how much evidence is needed to justify a strike?
The Obama administration has never spoken publicly about signature strikes. Instead, generally anonymous officials have offered often vague examples of signatures. The resulting fragmentary picture leaves many questions unanswered.
In Pakistan, a signature might include:
A group of guys2026
Officials have characterized the intelligence that goes into these strikes as thorough, based on “days” of drone surveillance and other sources 2014 and said that apparently low-level people may still be key to an organization’s functioning. In 2010, an official told the Los Angeles Times that the CIA makes sure “these are people whose actions over time have made it obvious that they are a threat.”
In Yemen, signature strikes are reportedly bound by stricter rules. Officials have often cited the necessity of a plot against Americans:
These strikes are not supposed to target “lower-level foot soldiers battling the Yemeni government,” U.S. officials told the Wall Street Journal. A White House spokesman said last summer that the U.S. “[has] not and will not get involved in a broader counterinsurgency effort” in Yemen.
But experts say some strikes in Yemen do appear to have been aimed at local militants. In Pakistan, in addition to low-level militants who might be involved in the war in Afghanistan, the U.S. has sometimes hit those who posed a threat to the Pakistani government.
As we detailed, signature strikes have also been criticized by human rights groups and some legal observers because of the lack of transparency surrounding them, including on the number of civilians killed.
