Yes, Mr. Netanyahu is in many respects "a disappointing, risk-averse leader." But U.S. policy is not helping matters. When Obama asked Netanyahu to agree to a second building freeze, he demanded nothing equally politically suicidal from Abbas. That sort of inequity prolongs the conflict.
Wait. If what the Pals. propose can be "suicidal", what's the problem with Israel's Prime Minister being a "risk-averse leader"? What is so disappointing?
Is there anything else the United States does - or does not do - that is not helpful?
