We non-Muslims cannot solve the problem; we cannot brainwash them out of their fundamentalist beliefs. The Islamicists last week horribly and irrefutably asserted the supreme importance of that faith, overriding all worldly considerations, and it will take a huge effort of courage and skill to win round the many thousands of British Muslims who are in a similar state of alienation, and to make them see that their faith must be compatible with British values and with loyalty to Britain.
