Peter Bergen wrote for CNN about the state of terrorism 16 years after September 11, 2011, drawing on data from International Security's recent report:
Sixteen years after the 9/11 attacks, there is a fair amount of good news about the state of the battle against jihadist terrorists: The United States has not suffered a successful attack by a foreign terrorist organization since al Qaeda's horrific attack on the World Trade Center and Pentagon.
Al Qaeda's core group, based in Afghanistan and Pakistan, hasn't launched a successful attack in the West since the suicide bombings on London's transportation system more than a decade ago in 2005, which killed 52 commuters.
The terrorist group that sprang up in the wake of the setbacks suffered by al Qaeda, ISIS is itself now largely defeated, having lost the city of Mosul, its headquarters in Iraq, and much of the city of Raqqa, its headquarters in Syria.
