I didn't know about this before, thanks :|

I thought he was much more of a moderate in Netanyahu cabinet.

There's a large attempt to pin all of this on Netanyahu and his closest cabinet but what he's saying is pretty much supported by nearly all of Israeli society down to individual citizens. I encourage everyone to find people who live in Israel on X and translate their tweets so they can see for themselves.

He is a moderate; which tells you all you need to know about contemporary Israel politics and ethical standards.

Liberal Zionists like to pretend Gallant was the "moderate one" but in reality there is essentially no moderate in current Israeli society, there is only the secular far right and the messianic further right. The two differ only in small derails of their preferred strategy when using the military to ethnically cleanse Gaza. There is no significant coalition that recognizes basic human rights for Palestinians.

He is a member of Netanyahu's party, which is a right-wing party (though not far-right in terms of Israeli politics).

He is certainly not a moderate, but he is far more trusted than Netanyahu and is considered a moderating and opposing influence on him by many people. Mostly representing the interested of the defence establishment, as opposed to purely political interests (or, if you ask me, as opposed to Netanyahu's only real interest, which is himself).
