A second intelligence officer, who spoke to BuzzFeed News via encrypted app and also spoke on condition of anonymity, confirmed that Israel had shared specific intelligence with the US regarding an active threat to US-bound planes. Speaking to BuzzFeed News via a military base in northern Israel, he said Israeli intelligence officers were "boiling mad and demanding answers" as to whether Israel's military would continue its current intelligence-sharing agreement with the US.
Israel still maintains a large network of human assets, also known as HUMINT, who work in gathering intelligence on the ground in countries across the world. Unlike other western countries, who have given up costly HUMINT operations in recent years in favor of signals intelligence or SIGINT, intelligence gathered through online systems, phone lines, and other communications Israel still invests heavily in sending its own spies abroad and in cultivating a network of locals interested in selling or trading intelligence.
The Ministry of Defense official who spoke to BuzzFeed News said the network of resources Israel maintained made their intelligence both, "incredibly valuable and precarious," adding that real human lives were put in danger if that intelligence leaked out to the wrong parties.
The Israeli officials who spoke to BuzzFeed News said there has already been a push to stop sharing Israel's most sensitive intelligence with Trump's White House. It was Israel's political echelons, they added, who insisted the intelligence-sharing continue, and who were hoping to use Trump's mistakes as a way to gain leverage.
