"The barriers to a two-state solution are well known. As a strong friend of Israel, I admit freely, but with great regret, that these include the expansion of settlements on the west bank. Settlement building is wrong. It threatens the viability of a future Palestinian state—the case for which is unarguable. It does immense damage to Israel’s standing in the world, and, over time, it will put at risk that which is most precious about Israel’s character: its Jewish and democratic character. However, as Secretary of State Kerry stated clearly, this is not to say “that the settlements are the whole or even the primary cause of this conflict.”There is also the incitement tolerated, and, in many cases, perpetrated by the Palestinian Authority. I am talking about the payment of “salaries” to those convicted of terrorist offences, and the naming of schools, streets and sports tournaments after so-called martyrs, thereby glorifying their violence. Then there is the greatest barrier of all: the rejectionist, anti-Semitic ideology of Hamas, Hezbollah and Iran, which denies Israel’s very right to exist, and the terrorism that inevitably flows from it."
