Weeks ahead of Israeli elections, Palestinian officials are already plotting a series of tough steps against Israel to be taken if, as polls predict, Prime Minister Benjamin Netanyahu is re-elected and peace efforts remain stalled.

Emboldened by their newly upgraded status at the United Nations, the Palestinians are talking of filing war crimes charges against Israel, staging mass demonstrations in the West Bank, encouraging the international community to impose sanctions, and ending the security cooperation that has helped preserve quiet in recent years.

These plans, combined with growing international impatience with Israeli settlement construction on occupied land, could spell trouble and international isolation for the Israeli leader.
