FYI the IDF might have even had some clandestine help in the freedom of Rav Hutner.
Even though the Jordanians fought the Israelis in the 6 day war, they werent exactly enemies . They both had the same enemy (The Palestinians) and the Israelis helped King Hussein defeat Black September when they tried to overthrow King Hussein shortly after the Dawson Field Hijackings . Its likely Military intellegence at the very minimum was shared in the Dawson Field Hijacking to free Rav Hutner and the other Hostages
