Tom Friedman writing in the New York times:-

……no laws or walls we put up will ever be sufficient to protect us unless the Arab and Muslim societies from whence these suicide bombers emerge erect political, religious and moral restraints as well — starting by shaming suicide bombers and naming their actions “murder,” not “martyrdom.”

Murder is about other people; martyrdom is about themselves.  It’s the ‘me, me, me,’ thing again.
