Bill's right, as far as it goes. What he doesn't do is lay the blame where it belongs, at the feet of the Saudi monarchy & Israeli expansionism.
The Saudis exploit radical Islam at home to hold power even as they export Jihad as a safety valve. The Wahhabis have been their allies & enforcers since Saud consolidated control back in the 1920's. Acquisition of enormous wealth allows for much more expansive efforts than ever before. The most radical elements are encouraged to spread their version of Islam- somewhere outside the Kingdom, of course. Their efforts are well financed, as well.
All the stuff Bill said about us, about the tolerant & egalitarian nature of Western Society doesn't really apply to our Israeli friends at all no matter what we'd like to believe. Yet they are the face we put forward to the Islamic world around them.
