JERUSALEM (AP) — Israel’s prime minister has rejected a key aspect of President Barack Obama’s policy speech, saying that a return to his country’s 1967 borders would spell disaster for the Jewish state.

In a statement released late Thursday, Benjamin Netanyahu called the 1967 lines “indefensible.”

The tough stand could set the stage for a tense meeting Friday when Netanyahu goes to the White House.

In his speech, Obama said a future Palestinian state must be based in territories captured by Israel in the 1967 Mideast war, with minor adjustments reached through negotiations.

Netanyahu said such a withdrawal would jeopardize Israel’s security and leave major West Bank settlements outside Israeli borders.
