Binyamin Netanyahu has told US congressmen that Israel both wants and needs peace and a two-state solution, but that he would not accept a "return to the indefensible boundaries of 1967".
Echoing Ronald Reagan's famous speech in Berlin in 1987, the Israeli Prime Minister called on Palestinian President Mahmoud Abbas to "tear up your pact with Hamas and make peace with the Jewish state".
Twelve years later, two of Israel's longest-serving statesmen are still at it, with Binyamin Netanyahu as Prime Minister and Ehud Barak his coalition partner and Defence Minister, now of the new Independence Party.
For a man who has spent over two decades working within the world of diplomacy and mastering the art of providing carefully crafted, nuanced responses on behalf of the government of Israel, Mark Regev could hardly be more blunt.
The leaders of Israel and the United States are to meet in Washington later this month.
Israeli Prime Minister Binyamin Netanyahu, who is visiting London and Paris this week, is due to address a joint session of the US congress on May 23. The meeting with President Obama will take place at the White House three days earlier.
A serious rift between the British and Israeli governments opened up this week during the visit of Binyamin Netanyahu to London, over the welcome given by David Cameron to the unity deal between Fatah and Hamas.
Israel is understood to be furious that William Hague and Mr Cameron had both made positive public statements about the new pact.
