premise: Sneh said the overnight arrests were aimed at preventing attacks and said the army would continue to operate in the West Bank "to prevent suicide attacks."
  Palestinians want the truce to be extended to the occupied West Bank and on Sunday, the al-Aqsa Brigades, a group loosely affiliated with president Mahmud Abbas's Fatah party, gave Israel two weeks to enact such a measure or risk renewed rocket attacks from the Gaza Strip.
  Under the terms of the truce, Israeli forces withdrew from Gaza and militants were supposed to stop firing rockets into the Jewish state from the coastal strip.
  Although a handful of such rockets have been fired since in violation, without causing damage or casualties, the truce has held.
  On Sunday Israel's security cabinet decided to continue a policy of restraint in the face of the violations, although Prime Minister Ehud Olmert warned that the policy could be scrapped if rocket fire continued.
   What is more likely to happen to the policy of restraint if the Palestinian violations continue?
hypothesis: could be scrapped
