...Well that is a problem then. Any good leader should want peace...
It's not a problem.
The primary role of any national leader is to ensure the survival of his nation, regardless of his personal desires.
All else - including peace - is secondary.
Also, it is also slightly difficult to make peace with those who have sworn to erase your nation from the face of the earth and to drown you and your people in the sea.
...Yes we give them free arms and we get what again?
Advance bases, a tripwire, and a bulwark against the savages of the Middle East. A buffer, and an ally that isn't too chickenshit to actually fight.
