The Trump peace plan tells the Palestinians that the sensible question is not whether a deal provides everything you think you are entitled to, but whether it is the best deal available. If their demands for “justice” include Israel’s destruction, it says, the United States will not support them and will not fight to preserve the status quo for their benefit. A notable feature of the plan is the warning that, if the Palestinians continue to reject peace unreasonably, the US will not block Israel from advancing its own claims to areas that, in the administration’s view, realistic peace talks would leave to Israel.
