Problems start back home, in poverty, with bad parents and poor role models, the children given no mentors or guidance as they're ignored by society at large. The only available guidance they receive - the dirty words from religious clerics and violent lyrics from music. It's all about becoming indoctrinated with vile bile.
Western states, namely the US and the UK, have known for years that military aggression in the Middle East fuels anti-Western extremism, and that's exactly what they persist in doing. Until they address this, there will never be an end to this bloody ideological clash between 'Western imperialism' and 'Islamism'.
Six weeks ago, I wrote: "We should be in no doubt: we, the West, are back in Iraq." And so it has come to pass. It is difficult to see how it could have been otherwise, once the murderers of Islamic State (or Isis or Isil, take your pick) started killing American and British journalists and aid workers on video. ... We have entered a bizarre Alice in Wonderland world in which Washington, Tehran, Damascus, Riyadh and Doha all seem to be lining up on the same side. The Saudis, Qataris and Emiratis even seem to have deployed some of their own aircraft, which I suppose at least proves that they do know what they're for.
Meet 20-year-old Hamza al-Britani who left Birmingham for Syria in June last year. The British Pakistani told me via Skype how he caught a plane to Turkey and simply "jogged" over the border to "the land of jihad." A family friend of Hamza had arranged this interview so he could clear up misconceptions about jihad and ISIS...
To save lives and protect human rights, the genocidal fundamentalists of ISIS must be stopped. But not by the West and not for the reasons often advanced by David Cameron and Barack Obama... The truth is that if the US and UK are serious about fighting ISIS they should start by aiding the people on the ground who know the region best, have local roots and who are already leading the fight against the jihadist menace - the peshmerga army of the Kurdish regional government in Iraq and guerrillas from the Kurdistan Workers Party and allied movements in Syria.
Islamic State's blood-thirstiness has been much commented on, as has its use of modern technology. Posting videos of a man issuing threats before killing a hostage ... this is the "new normal" for Islamic State comms, but somehow it's exercised a strange power over many western commentators and politicians.
Air strikes alone won't defeat ISIL. The organisation is clearly goading the West into direct confrontation. Once we get the first pictures of Muslim women and children killed by US missiles, no matter how isolated these incidents would be, that would up the ante in ISIL's propaganda war. This is when allies like Saudi Arabia and Qatar will get cold feet.
