He was eulogized by President Reuven Rivlin and Prime Minister Binyamin Netanyahu.
Among the American Betarim present were Izzy Herman, Steve Adler, Dov Hertz, Reuven and Rena Genn, Baruch Kraus, Chaim Fischgrund, Nissan Teman, Danny Krakow, Wilma Friedman and Yisrael Medad.
I few excerpts from Misha's autobiography published last year:
His "Flags Over the Ghetto" was a major contribution to, literally, righting the history of Betar.
We usually met at the annual memorial ceremony for Jabotinsky, which this year Misha missed, if not listening to his lectures:
From former Netziv Yitzchak Heimovitz:
Misha Arens was a man "sans peur et sans reproach" Without fear and without reproach. If you wanted to know what a perfect Betari was, you only had to look at Misha.
He was Netziv in the U.S. and gave that up in order to rush to Israel to fight in the War of Independence. In the early 1950's he and Muriel returned to the US with their firstborn son, for Misha to complete his graduate studies in aeronautical engineering,
Then they went back to Israel where Misha became a professor at the Technion, and I think he founded the aeronautical engineering department there. After some years Misha became head of the Engineering Department of Israel Aircraft Industries. (IAI) for many years.
In August 1970 Misha told me he was ready to return to activity in the movement. I wrote Menachem Begin, who said Misha should talk with Haim Landau. The rest, as they say, is history.
Sheldon Lerman sends this:
Toldot Yisrael had the opportunity to interview Moshe Arens several years ago about his early remembrances of Jabotinsky and his leadership within Betar in the United States. The full one hour interview in English is viewable here: https://youtu.be/
