Anyone thinking there will be a Israeli-Palestinian “peace” as long as there is an Israel is a total nutjob.
I understand what you mean with respect to the present Pali "leadership," but there is sometimes a fine line between being an idealist/eternal optimist and "nutjob." But Abbas is not the man for Israel to make "peace" with; his record speaks for itself.
There is no “palestine” nor any so-called palestinians but for various conglomerations of predominantly islamist arabs who, for whatever God forsaken reason, Israel feels compelled to have to put up with.
