It’s not difficult. I apparently guessed your sentiment accurately even though I was actually describing the first head of state to be convicted of war crimes for promoting genocide and ethnic cleansing.
But, let’s make this even less difficult. Is the goal here security or dominance? Security suggests reducing hostilities but dominance suggests removing a group of people from an area of land. I really don’t see any reduction of hostilities.
In Israel case, its "we have to get them so they don't get us again". Not sure why this is so difficult to understand.
Not sure why you haven't bothered to read the rest of my comment as I addressed your two other points.
