Prime Minister Benjamin Netanyahu, at the outset of his meeting with US Senator Lindsey Graham (R-South Carolina), said Israel was faced with two “great challenges.”The first, he said, “comes from the Palestinians. The chief Palestinian negotiator, Saeb Erekat, has compared Israel to ISIS. This is the same Palestinian Authority that joins hands with Hamas, incites constantly against Israel...and is going to try to bring to the UN Security Council a resolution that seeks to impose on us conditions that will undermine our security. And I want to assure you that we will stand firmly and reject such a dictate. We always have; we always will.”The other great challenge facing Israel, Netanyahu said, comes from Iran, which he noted on Saturday carried out a military drill on Saturday with a “suicide drone” near the Strait of Hormuz.Netanyahu told Graham that "the most important task before us is to prevent this dangerous regime from having nuclear weapons. And I believe that what is required are more sanctions, and stronger sanctions."
