Of course, one line of argument claims that if we just left all these places alone then none of this would come to us. But we left the Balkans alone and created one generation of jihadists. Then we didn’t leave Afghanistan and Iraq alone — and created another generation of jihadists. Now we have very much left Syria alone — and lo and behold, we seem to have created another jihadist generation. Damned if you do, damned if you don’t, apparently. Yet remarkably few people seem to realise that this isn’t really about us.
Nevertheless, it comes ever closer to home. In recent weeks the black flag of jihad as used by Isis has been flown openly in London — supporters of Isis have appeared on Oxford Street — and elsewhere. Just this week, the imam of a leading Welsh mosque resigned after a pro-Isis guest preacher was invited to speak at his mosque.
This battle is going on in households and mosques up and down this country. We fear joining up these dots. And we fear giving offence more than we fear the international opprobrium that is coming our way.
The country that brought liberty to much of the world is now exporting terrorism to large parts of it. Britain needs to look to itself, and address this problem, if there are not to be many more videos like this week’s.
