Israeli Prime Minister Benjamin Netanyahu is in Washington on Friday for talks with U.S. President Barack Obama. The two leaders are expected to discuss their disagreement about the borders of a future Palestinian state. In a widely publicized speech on Thursday, Obama said a Palestinian state should exist within the borders that were in place before Israel captured much of East Jerusalem, the West Bank, the Gaza Strip and the Golan Heights in 1967. But Netanyahu said those borders would leave Israel “indefensible.” On Friday, his office released a statement saying that they feel Washington doesn’t have a full understanding of Israel’s security concerns. Meanwhile, Arab League chief Amr Moussa urged Obama to stay true to his endorsement of the 1967 borders, saying peace talks should not just focus on Israeli security.
