Christiane Amanpour on CNN this morning in an interview with Baroness Warsi happened to mention Masood, "the Westminster Terrorist", saying that "we still don't know what motivated him". Oh yes, we do! I yelled at the screen. It's in the Koran. It's the doctrines of Islam (The "Trinity of Islam"). I've said similar things countless times over the years. And so have reliable observers like Sam Harris.
Here in this post from Areo, a new website I've been following lately courtesy of Professor Jerry Coyne, on his "Why Evolution is True" website, is one of the best and clearest expositions of what it that motivates Islamic terrorists. In short: Islamic doctrine. Not grievances about western foreign policy. (Of course, grievances are a part of it. But the Islamists/jihadists make it clear that even if all the grievances were resolved, they'd still hate and attack us).
The ISIS magazine Dabiq article, mentioned in the Areo post -- "Why We Hate You and Why We Fight You" [p.30] -- is well worth reading. It's brutally and soberingly clear about the Islamic reasons, the doctrinal reasons, they hate and fight we infidels. (Sam Harris reads the Dabiq article).
"Westminster and the Islamic Connection" [the conclusion]:
This utter confusion and determined ignorance among westerners as to what constitutes Islam and what inspires jihadists, is presumably the reason why a Muslim attacking civilians with a car in accordance with Islamic State directives and having a "clear interest in jihad", has the police and public so mystified as to his motives. Speaking on the attack, Metropolitan police commissioner Neil Basu said the following:
The understanding of his motives did not die with Masood. It died long before. It died the moment we decided as a society that we would repeatedly treat attacks of this kind with platitudes and self-delusion and willful ignorance, in preference to confronting the ideology that inspires them. And as such, it seems that our collective instinct for self-preservation has died with it.
