It was apparently 2 VCs and not the military that came up with GHF (and if I recall, there even was a brief flare up between the ruling Cabinet and the Chief of Staff, Eyal Zamir, who did not want the IDF to be responsible for aid).
Even though the early planning was led by the Israeli military, two Israeli technology investors played an influential role in shaping discussions as they progressed, according to six Israeli and American individuals familiar with the GHF’s origins. One was Liran Tancman, an entrepreneur and reservist in the IDF’s 8200 signals intelligence unit, who called for using biometric identification systems outside the distribution hubs to vet Palestinian civilians. Another was Michael Eisenberg, an American Israeli venture capitalist who argued that existing U.N. aid distribution networks were sustaining Hamas and needed to be overhauled.
