Question.

JERUSALEM (AP) - Israeli Prime Minister Ehud Olmert said Sunday peace talks with the Palestinian coalition government would be impossible as long as it refuses to renounce violence and recognize Israel's right to exist.
...

The coalition platform, however, appears to implicitly recognize Israel by calling for a Palestinian state on lands the Israelis captured in 1967, in contrast with Hamas' past calls to eliminate Israel altogether.

It also pledges to ``respect'' previous agreements with Israel and authorizes Abbas to conduct future peace talks. Any future deal would be submitted to a national referendum, apparently taking away veto power from Hamas.

As recently as last march Israeli leader Ehud Olmert reaffirmed his belief in the concept of Greater Israel including the occupied territories, in a speech to the US Congress no less:

I believed, and to this day still believe, in our people's eternal and historic right to this entire land.

To be clear this means that the leader of Israel denies the right of Palestine to exist. Government Minister Avigdor Lieberman has in the recent past, gone so far as to advocate ethnic cleansing to achieve Greater Israel.

Are the government of Israel or it's Ministers required to renounce such views and affirm the State of Palestine's right to exist? Should they be?
