I am amused that you think its 'my definition'.Notwithstanding my disagreement with your definition of “illegal occupation” and “occupation” lingo,
I think that the phenomenon of one side winning and the other one losing, and then both moving on is the norm of the human society throughout the history.
Its the definition agreed by the ICC, ICJ and voted on by the UN.
Israel is illegally occupying Palestine and has been ordered to end the occupation.
