The Palestinian Authority says it will use violence, if neccessary, against Palestinian terrorists, to keep the peace. Palestinian police are arresting terrorist leaders, and compiling information on the Palestinian terrorist groups. But the real crunch comes later, when the Palestinian terrorist groups threaten to fight back. In the past, when it got to this point, the Palestinian Authority would back off. No one is sure what will happen when the next face off occurs, and it is likely to happen in weeks, or months.
