‘Duty to warn’ helps avert catastrophes 

The U.S. warns countries, even adversaries, about intelligence that indicates potential attacks if conditions allow. But that doesn’t mean the other side has an obligation to listen.

WASHINGTON (AP) — The U.S. warning to Russia couldn’t have been plainer: Two weeks before the deadliest attack in Russia in years, Americans had publicly and privately advised President Vladimir Putin’s government that “extremists” had “imminent plans” for just such slaughter.

The United States shared those advance intelligence indications under a tenet of the U.S. intelligence community called the “duty to warn,” which obliges U.S. intelligence officials to lean toward sharing knowledge of a dire threat if conditions allow. That holds whether the targets are allies, adversaries or somewhere in between.

There’s little sign Russia acted to try to head off Friday’s attack at a concert hall on Moscow’s edge, which killed more than 130 people. The Islamic State’s affiliate in Afghanistan claimed responsibility, and the U.S. said it has information backing up the extremist group’s claim.

John Kirby, the Biden administration’s national security spokesman, made clear that the warning shouldn’t be seen as a breakthrough in U.S.-Russian relations or intelligence-sharing. “Yeah, look, there’s not going to be security assistance with Russia and the United States,” Kirby told reporters Monday.

“We had a duty to warn them of information that we had, clearly that they didn’t have. We did that,” Kirby said.

Here’s a look at the duty to warn, how it came about, and how it can play out when American intelligence officers learn militants are poised to strike.


On March 7, the U.S. government went public with a remarkably precise warning: The U.S. Embassy in Moscow was monitoring unspecified reports that “extremists have imminent plans to target large gatherings in Moscow, to include concerts.” It warned U.S. citizens in Moscow to avoid big events over the next 48 hours.

U.S. officials said after the attack that they had shared the warning with Russian officials as well, under the duty to warn, but gave no details how.

Putin’s public reaction was dismissive. Three days before the attack, he condemned what he called “provocative statements” from the West about possible attacks within Russia. Such warnings were aimed at intimidating Russians and destabilizing the country, he said.


The U.S. emphasis on sharing threat warnings increased after al-Qaeda’s Aug. 7, 1998, attacks on the U.S. embassies in Kenya and Tanzania. While dozens of U.S. citizens and government employees of different nationalities were killed, Kenyans made up the majority of the victims.

In 2015, then national intelligence director James Clapper formalized duty to warn in an official directive: The U.S. intelligence community bore “a responsibility to warn U.S. and non-U.S. persons of impending threats of intentional killing, serious bodily injury or kidnapping.”


The intelligence community under former President Donald Trump faced accusations it had failed to warn U.S.-based journalist Jamal Khashoggi of a complex plot by Saudi officials that ended with his 2018 murder inside the Saudi consulate in Istanbul. 

U.S. intelligence agencies did not respond to requests for any records showing whether they knew of the plot in advance.

Under the Biden administration, the sharing of threats to other governments has flourished, although there’s no way to know of any threats that the U.S. intelligence community may have decided to let play out, without warning the targets.

Strategic U.S. dissemination of intelligence hit a high point in the months before Russia’s February 2022 invasion of Ukraine. That’s when the U.S. opted to declassify key intelligence on Russia’s invasion plans to rally allies and Ukraine, and — unsuccessfully — to pressure Russia to call off its troops.
