The greetings President Obama extended last week to Israel’s new government may have sounded conciliatory, but Mr. Obama no longer entertains any illusions about Israel’s leaders.

In the wake of last month’s election, the longtime peace activists and diplomats who have devoted much of their professional lives to achieving a two-state solution to the Israeli-Palestinian conflict are more depressed and demoralized than ever before.

Well before Mr. Netanyahu declared during the recent election campaign that Palestinians would remain under Israeli military occupation as long as he is Israel’s prime minister, Mr. Obama understood that the Israeli government’s enthusiasm for continued peace talks with the Palestinians served no purpose other than to provide cover for Israel’s continued expansion of Jewish settlements and to preclude the emergence of anything resembling a Palestinian state in the West Bank.

Faced with this grim reality, some observers naïvely rooted for the center-left Zionist Union during the campaign. But the notion that a government led by Isaac Herzog and Tzipi Livni might have produced a two-state accord with the Palestinians was also a delusion. An agreement based on the 1967 lines never appeared in the Zionist Union’s platform or crossed Mr. Herzog’s lips.
