The United States and allies seem to lack a clear strategy for toppling the terrorist threat 16 years after the worst terrorist attack in American history, experts say.
Since 9/11 attacks, there have been another 97 terrorist plots against the United States, and the bulk of those 15 successful attacks happened in the last six years. according to a database maintained by The Heritage Foundation.
A total of 27 of the overall plots came from the Islamic State, said David Inserra, a homeland security policy analyst for The Heritage Foundation said Friday during a panel.
“The variable explaining this is ISIS,” Inserra said, explaining the uptick in attacks in recent years. “Something changed, ISIS occurred.”
