Alon Pinkas writes to say that while he agrees that American policy has been to call for 1967 borders as Israel's borders since 1967. But he adds:
"I'll tell you where there is something significantly new (albeit in a speech, rather than in reality): at Camp David, in July 2000, and later in the "Clinton Parameters" of January 2001, the concept was that a deal would include the "End of conflict and finality of all claims." That was Barak's and Clinton's premise and prerequisite.
Obama is essentially saying that a Palestinian state should be established BEFORE Jerusalem and the refugees issues are resolved. That's a change.
