From the UK's Mirror web site:
We know very well what the "grievances" of the jihadists are.
The grievance of seeing unveiled women. The grievance of the existence, not of the State of Israel, but of the Jewish people. The grievance of the heresy of democracy, which impedes the imposition of sharia law. The grievance of a work of fiction written by an Indian living in London. The grievance of the existence of black African Muslim farmers, who won't abandon lands in Darfur. The grievance of the existence of homosexuals. The grievance of music, and of most representational art. The grievance of the existence of Hinduism. The grievance of East Timor's liberation from Indonesian rule. All of these have been proclaimed as a licence to kill infidels or apostates, or anyone who just gets in the way.
The grievances I listed above are unappeasable, one of many reasons why the jihadists will lose.
They demand the impossible - the cessation of all life in favour of prostration before a totalitarian vision. Plainly, we cannot surrender. There is no one with whom to negotiate, let alone capitulate.
To that I can only add a loud and thunderous "amen".
