Bullcrap. It was the British who has started with islamist extremism back to a late 1940s to undermine both US and Soviet influence in the Middle East. Israel was specifically targeted because it wasn’t clear at the time will it be a US or USSR client and the British couldn’t afford a direct diplomatic confrontation with either superpower. Hizb-ut-Hahrir was the first terrorist organization as we know it and it’s function was to push around new ME players and help the British if not to keep their Empire to at least stay a mediator. All the rest of terrorist organizations there are rooting from it.
They created a monster that they cannot contain.
