Besalel: While the “grunts” (a mid-20th century American term for ground forces, usually infantry) are increasing right-wing, the high tech (as well as American support) is what keeps Israel safe from attack from Iran and any major power whose intervention would include nuclear weapons. It is the high tech types in the IDF who are threatening to mutiny. While the “right” would win the ground war in a civil war, the country would be horribly vulnerable to someone such as Russia or China or Pakistan choosing to wipe Israel at a distance in order to support throughout the Islamic world.
P.S. The only sort of compromise that might work would involve allowing the upper class to be an autonomous minority with a Jewish state (we let them be frei, and they don’t object to us being frum). The would mean an military that operates as if everyone was frum, with special secular units for those who can’t stand kosher food or not doing melachos on Shabbos, secular “hesder” institutions or them to study their culture, and letting the seculars (regardless of whether they are Jews according to halacha) marry whomever and whatever they want, and even allow the secular to kill their own babies.
Whether such a compromise would interest the seculars is questionable, since a major theme of the zionist dream was always to purge Torah for Jewish life. However as the current crisis has shown, no matter how frum the average Israeli becomes over time, the economic elite are the ones who run the show, leaving Israel as both unstable and undemocratic.
