War on terror was US adventurism that has no basis in the international law. UN never authorized this. US just likes to play world police. Really that simple. Meanwhile, Islamic terrorism is the direct product of US overthrowing secular and socialist governments around Middle East using groups like Mujahideen that have now evolved into IS and the Taliban.

US is a scourge upon humanity, and the sooner it gets pushed out of the Middle East the better things will be for the people living there.
