Gilles Kepel, French multilinguist author, recently wrote Terror in France which is at googlebooks in English, in preview fashion*. I have here from his p. ixx a reference to jihad ideology:
published online in 2015 and disseminated through ISIS social networks under the title How to Survive in the West. A Mujahid's Guide 2015:
"A real war is heating up in the heart of Europe....The leaders of disbelief repeatedly lie in the media and say that we Muslims are all terrorists, while we denied it and tried to be peaceful citizens. But they have cornered us and forced us into becoming radicalized, and that will be the cause of their defeat and the cause for the conquest of Rome. The people who own the media have had Europe and the Western world as their stronghold for over a 1000 years, they do not want Islam to rise in their stronghold. They want to keep their authority, their adultery, wine and money and do not want to lose it. So they are doing a multibillion dollar media campaign to stop the Islamic State in the Middle East and a multibillion dollar media campaign to stop the rise of real Islam in the West....It is a matter of life and death for both; only one will survive. Allah's last messenger Muhammed (peace be on Him) promised us we will win and finally take over Europe's capital, Rome, but only after we have taken Persia...."
