The Obama administration's flagging efforts to revive Arab-Israeli peace talks took another turn in the wrong direction this week. The Palestinians overcame U.S. opposition and won diplomatic recognition by UNESCO, becoming a new member state of the U.N.'s cultural and scientific agency. They've vowed to keep seeking such recognition elsewhere in the U.N system. Israel responded by speeding up settlement construction. U.S. officials say those moves are pushing the parties further away from a peace process, but both sides seem determined to move in opposition directions, leaving the U.S. looking weak and isolated on this issue.
