What does a vote for early elections really mean, it1s a sign of no confidence for the central leadership of the country, especially the prime minister. The most important difference is the nature of Israeli politics. In Israel many political leaders represent ideologies. By definition they are not capable of compromise. The Knesset members representing Moledet, Rehavaam Zeevi and Rabbi Benny Elon are not about to change their ideology in exchange for a promise to eliminate the clauses in the Palestinian National Charter which call for Israel1s destruction.
Ideologies develop over years.
By definition, they cannot be wrong. They might be mistaken or the foundations upon which they were based may have changed, but they do not change or compromise easily. In general, politics is full of compromise and politicians have little problem dealing with compromises. But in Israel, things are different. Politicians are supposed to be ideologues.
