The United States is likely to face a higher risk of Islamic State-inspired attacks over the next two years as the group loses land in the Middle East, a top official with the Federal Bureau of Investigation said on Wednesday.
"I'm fairly convinced that 2017 and 2018 in the homeland will be more dangerous than we've seen before, because as we shrink ISIS, they'll lash out," Michael Steinbach, executive assistant director of the FBI's national security branch, told a security conference at the Massachusetts Institute of Technology.
