Maybe...
Overall, though, I am with Julian in his hatred of Islam. Not a view I have come to without some soul-searching. Sorry if that offends any well-meaning but impotent liberals in these parts.
Not that I side with our glorious political leaders and their actions in the Middle East which have made their own unique and malign contribution to current events. But I was over in Paris in 1995, and Islamic terrorists were killing people there even then. Well before 9/11 and the subsequent invasion of Afghanistan and Iraq. Plus ça change.
Jihadi John died far too painlessly. Hilariously, I have heard that Jeremy Corbyn would have preferred his arrest and trial. Words fail me on that view...
BTW, the ones to feel sorry for are the poor bastards who just went out on a Friday night to enjoy themselves and didn't make it home. And their families and friends.
Made no sense then. Makes even less sense in this case given that this is a borderless conflict.
Look at where the funding comes from and start there. Though I don't remember anyone here in that era baying for the RAF to bomb Boston or Philadelphia in retaliation for US contributions to Noraid.
I would steer away from stigmatising a billion and half plus individuals who like you and I are just trying to get by. We know exactly where that train of thought ends if it gains momentum.

In the case of Isis, they exist because America and its "coalition of the willing" overthrew the governments of Iraq, Libya, and destabilized Syria to such an extent there is no political force capable of countering Islamic fundamentalism.
The fact that the main victims of both Isis and the Taliban are fellow Muslims should alert you to the fact that the vast majority of Muslims do not agree with these groups. Had we (the West, plus Saudi Arabia, Qatar and Turkey) not overthrown the governments of the areas where Isis chiefly operates, I'm sure the Muslims there would have "taken care of their shit" quite effectively.
