Here is some political party suggestions.

i was actualy suprized about the research that has been done! i didnt expect to put much effort on the parties :D
so i taken the focus "support herut". just casue i love to conqer sh*t XD
I was suprized to see that the "herut" party didnt exist and wasnt the thing getting boosted. instead another nationalistic religious party did.
and the leader that was boosted is a random person.
I will reccomend changing the nationalistic party "agudat israel" to simply "Herut"
and set the leader of said party to "Menachem Begin". herut was a big party back then and its leader actualy got elected irl later down the line,
he is actualy considered an important historical figure as a prime minister here.
it just makes more sense as it fits the focus and we already have 3 or more options for orthodox and ultra-orthodox parties. some secular nationalism(herut) would be good.
also, the conservative party,while ruling right now didnt exist up until 1973.

Last things:
During the six day war,Super Sherman was probobly the most known tank to be used by israel. my grandpa commanded one actualy. if you get the time its worth adding.
I think its cool you made all israeli aircraft,thought you will make all american.
Also loved the "Asking for orders,Copy" sound in hebrew when opening the army screen.
Thank you for doing extensive research and being such amazing bunch of modders. Hope to hear out from you guys!

P.S:Sorry for the long post,didnt post in in suggestions as a comment cause i wanted to make a detailed post.
