To get the terminology right, the “1967” borders wer actually the borders ending the 1948-1949 war of independence. They were not the UN partition borders, which made Jerusalem an international city. The 1948-1949 truce left the old city of Jerusalem in Jordanian hands, with no Jewish access to our holiest cites.
We tend to forget that those borders existed for only 19 years, while the territories liberated in 1967 have held for 44 years.
Even now, the holiest or most historic cites - the Temple Mount, Bethlehem, Hebron, and Jerico are in Muslim hands, with little or no Jewish access permitted.
I suspect that Obama has just guarenteed that the Israelis will never give another inch of territory, or to trust that the USA will protect them. Obama gives them little about which to be reassured.
Sure. He said, “Israel may defend itself, BY itself.” If that was not an invitation for invasion, I do not know what would be.
“To get the terminology right” they are not borders at all. They are ceasefire lines.
