Nudnik - n. U.S. colloq. Esp. in Jewish usage: a pestering, nagging, or irritating person
"Terrorism probes the world, tests its limits, and always redefines our moral awareness downward. We can't say for sure what the contribution of Yassin was to the wholesale slaughter of September 11. Strictly speaking, the "death pilots" were not his men. But in hindsight, the terrors visited on Israel by Hamas, Islamic Jihad, and the al-Aqsa Martyrs Brigades were a dress rehearsal for greater terrors to come. The young men--and, in time, the young women--with explosive belts in the streets of Jerusalem and Tel Aviv and the restaurants of Haifa were a herald of more terrible calamities. The way to perdition had been found: The cult of "martyrdom" had been sanctified. Religion had been remade; from solace and ritual it had been changed into a weapon of combat."
