The BBC reports:
"[. . .] the former prime minister said: "The reason why these people are radicalised is not because of something we're doing to them. They believe in their philosophy . . . Understand one thing - they believe in what they believe in because they believe their religion compels them to believe in it."
So he denies responsibility. Others become radicalised because of false beliefs about what their religion "compels" them to accept and not because of invading Iraq, etc. What then is the alternative causal explanation for increasing security threats? People feel compelled out of the blue?
The more time has passed since the invasion of Iraq the more we have seen the true poverty of the support for this shameful war. I suspect things will only become worse the more we learn about the decision to go to war and the planning behind operations.
