From Wesley Clark's website:

Every president since Harry Truman has kept America's commitment to the security of Israel. At Camp David, President Clinton helped the parties come close to peace, but Arafat balked and chose violence.

This is a variation on "the Palestinians reneged on Oslo" big lie, and on the "Barak's generous offer" big lie. Even Shimon Peres admitted that it was Israel who reneged on Oslo,

We have a skeleton, we didn't complete the house. The Oslo agreement has had a rather short occasion to implement itself, and that was between 1993 and 1996. The Oslo agreement was stopped in 1996 when the government in Israel was changed and Mr. Netanyahu became the Prime Minister. I think that the foundations and the structure of Oslo are still the best ones available. And once we shall have an opportunity, we shall complete the building that may withstand the winds of the outside world, and the skepticism of the people.

And according to Yitzhak Rabin, Arafat and the PLO were willing to work with him in stopping terrorism. (This was during the time when the Palestinians still had hope because they thought the Oslo agreement would be implemented)...

In the last two years, not one Israeli has been killed by PLO terrorism...

The "Barak's generous offer" big lie is exposed for what it is in these links:

If Clark wins the presidency, we will not see any progress toward peace in the Middle East while he's in office.

Here's what Kucinich has to say about it:

Of the candidates who address the subject of the Middle East in their websites, Kucinich is the only one who doesn't lie about it.
