It quotes Yigdal Carmon, here's an extract:
'The jihadis who perpetrate these horrific crimes are neither losers, nor nihilists, nor worshipers of death, nor sick cowards. On the contrary, the overwhelming majority of them are devout and fanatic believers. They are idealists who sacrifice their lives for the sake of a utopian future: a world ruled by their faith. The attacks they commit are extreme acts of piety. They seek to emulate the dedication of the early believers in order to revive the glory and grandeur of the past. In fact, as part of their training, many suicide bombers adopt a pious lifestyle: they immerse themselves in prayer, help the needy in their society, pay all their debts, and become moral and religious role models for others'
Don't expect the BBC or any UK politician to dare to repeat such thoughts.
