Amira Haas: Sooner or later, the next reprisal terrorist attack will come. Eleven Israeli victims, or 19, dozens of wounded, harsh scenes from the hospital, suffering of the families - these will prove the murderousness of the Palestinians, who kill Jews simply for being Jews. And this terrorist attack, or the one after it, which we will not forget and not forgive, will make it okay to cross another red line. On Monday, they waited for Yassin to leave the mosque. Is the day far off when the helicopter crew obeys an order to launch a missile or bomb at the mosque itself? After which it will be explained: there were four deserving-of-death terrorists inside, each with four armed escorts, and, anyway, the imam there refers to Jews as monkeys and pigs. And will the day arrive when an Israeli pilot fires a missile or bomb at a Palestinian mourning procession because marching in its two front rows are ranking members of Palestinian organizations, and right behind them are 30 armed masked men waving Kalashnikovs or Qassam launchers? Will that happen after or before the attack on a Jewish target abroad, which would take place after Hamas understands how hard it is, under conditions of a closure, to execute a local terrorist attack? That is when the new Hamas leaders will sprout.
