The Trump administration's Nuclear Posture Review retains a commitment, first made by Obama in 2010, not to "use or threaten to use nuclear weapons against non-nuclear weapons states that are party to the NPT [Non-Proliferation Treaty] and in compliance with their nuclear nonproliferation obligations." Today, all 184 non-nuclear weapons states under the treaty meet that criterion.

Trump's reaffirmation of this pledge, known as a negative security assurance, is significant. It rules out U.S. nuclear retaliation against these countries, even if they were to use chemical, biological, cyber or other weapons against the U.S. or its allies.

Much of the commentary on Trump's NPR has focused on how new, low-yield nuclear weapons and a focus on non-nuclear strategic attacks might lower the threshold for nuclear use. These concerns are justified. But they apply to a very narrow set of circumstances involving countries that already possess nuclear weapons, which have long been the focus of our deterrence strategies.

Using apps to prevent deadly police encounters

Mobile phone apps are evolving in ways that can stop rather than simply document deadly police encounters with people of color — including notifying family and lawyers about potential violations in real time.

Why it matters: As states and cities face pressure to reform excessive force policies, apps that monitor police are becoming more interactive, gathering evidence against rogue officers as well as posting social media videos to shame the agencies.

TikTok gets more time (again)

The White House is again giving TikTok's Chinese parent company more to satisfy national security concerns, rather than initiating legal action, a source familiar with the situation tells Axios.

The state of play: China's ByteDance had until Friday to resolve issues raised by the Committee on Foreign Investment in the U.S. (CFIUS), which is chaired by Treasury secretary Steve Mnuchin. This was the company's third deadline, with CFIUS having provided two earlier extensions.

Federal judge orders Trump administration to restore DACA

A federal judge on Friday ordered the Trump administration to fully restore the Deferred Action for Childhood Arrivals program, giving undocumented immigrants who arrived in the U.S. as children a chance to petition for protection from deportation.

Why it matters: DACA was implemented under former President Obama, but President Trump has sought to undo the program since taking office. Friday’s ruling will require Department of Homeland Security officers to begin accepting applications starting Monday and guarantee that work permits are valid for two years.
