Global economic instability also figures prominently as the top concern in a number of countries, and it is the second biggest concern in half of the countries surveyed. In contrast, concerns about Iran’s nuclear program as well as cyberattacks on governments, banks or corporations are limited to a few nations. Israelis and Americans are among the most concerned about Iran’s nuclear program, while South Koreans and Americans have the greatest concern about cyberattacks relative to other publics. And apprehension about tensions between Russia and its neighbors, or territorial disputes between China and surrounding countries, largely remain regional concerns.
