The state of Israel was founded to ensure the physical survival of the Jewish people, not the political survival of one man. Netanyahu forgot the difference and will pay the price.
As IDF generals, serving members of the Mossad, and elite combat reservists swell the ranks of opposition, his only allies are religious hardliners.
Should the current Anyone-but-Netanyahu ensemble collapse under the weight of its diversity, he stands a good chance of returning.
The opposition are allowing him first dibs at forming a government. This is a major risk for them, because he is a famed dealmaker.
