Ex-general Gadi Eisenkot, whose son died in Gaza, is emerging as a major political challenger to Prime Minister Benjamin Netanyahu in Israel's upcoming elections. Eisenkot, leading the centrist party 'Yashar!', criticizes Netanyahu's Gaza strategy and positions himself as a unifying, non-polarizing alternative. His military background and personal loss have bolstered his credibility among Israelis.
