Herzi Halevi replaced Aviv Kohavi as the IDF's 23rd chief-of-staff in a series of ceremonies on Monday.
There is no confirmation of when the video was taken, or if Avera Mengistu is still alive. He has been a captive of Hamas in Gaza since 2014.
The Israeli public trust in the country's institutions has drastically dropped over the last decade, yet, they still put their trust in the IDF.
Halevi and Kohavi will spend the day in a series of ceremonies, culminating in the Kirya military headquarters.
Kohavi had to deal with serving under four defense ministers, endless rounds of elections, COVID restrictions and the lack of a state budget.
The government of former prime minister Yair Lapid approved Halevi’s appointment on October 23.
Hagari will be the first IDF spokesperson to emerge from the navy.
What would be the stakes of a populist-run Israeli military? Will it actually happen?
New IDF chief Halevi knows that the greatest challenge he might face during his tenure has a better chance of coming from Israel’s political system than from Iran or Hezbollah.
Halevi, who will replace Lt.-Gen. Aviv Kohavi, will have his work cut out for him maintaining ties between the IDF and Israel's political echelon.
