"'It means we need to be perfect 100% of the time. They need to be perfect only once,' said Hans-Jakob Schindler, Sr. Director of the Counter Extremism Project, in an interview.
Schindler said terror groups are essentially waiting for the right opportunity to attack western countries.

...'In their eyes, they defeated the international community in Afghanistan,' he said. 'They defeated the international community and French forces, which are withdrawing from West Africa. In the grand scheme of things, the jihadists really feel they have the upper hand right now.'"
