About half of all Americans are “extremely or very concerned” about North Korea’s nuclear program, according to a new U.S. poll released Tuesday, with two-thirds of respondents also expressing serious concerns about cyberattacks.

The AP-NORK Center for Public Affairs Research survey of more than 1,700 adults from Aug. 12-16 found that 47% of Americans are very concerned about North Korean nuclear threats. The poll asked about the DPRK’s nuclear program along with 10 other threats, including the spread of misinformation, extremism, infectious diseases and climate change.
