The 1948-1949 territories were taken by Israel as a result of an Arab war to destroy the new State of Israel.
The 1967 territories were taken by Israel as a result of an Arab war to destroy the 19 years old State of Israel.
Those were facts, not possibilities, no matter what someone's propaganda says.
The right of Israel to keep the land taken in 1967 is the same right it has to keep the land it taken in 1948-1949.
That is what a logical person/ leader would say.
But politics aren't logical, they are dirty.
