This is a skewered view, to say the least. In fact, every Israeli government since 1967 has failed to live up to those proud liberal values by pursuing an expanded Israel ruling over a truncated Palestinian Bantustan, even if they did it under the guise of a "two-state solution."
Within weeks of the start of the occupation in 1967, the Allon Plan (under Labor prime minister Levi Eshkol) already proposed Israel annexing territory surrounding and isolating the Palestinian population centers. [...]
By Oslo’s end in 2000, there were 400,000 settlers in massive "settlement blocs" that fragmented the Palestinian territory into some 70 tiny enclaves of Areas A and B, plus the prison that is Gaza. Today, the settler population approaches 800,000.
If the two-state solution is gone, it is because of successive "sane" Israelis in government, in particular those of Golda Meir and Ehud Barak, as well as of the Likud, Kadima and the religious right, and the Zionist left, "hard" right, and the always malleable center that put them into office. [...]
But Yoffie is also wrong about how he characterizes what he calls the "hard left's" one-statism. Left groups who acknowledge the death of the two-state solution have not moved to a one-state alternative – at least not yet. Jewish Voice for Peace, which Yoffie demonizes because of its support for BDS, does not actively advocate for such a solution. And the rest of the "hard" left is still wrestling with where to go.
