Strange isn't it. Back in 1921, 4/5ths of their country is taken away and given to another country, yet they don't refer to it as "Occupied territory" nor do they stake any claim on it. One would think they would be a lot more excited about losing so much land by the edict of a foriegn country.
I imagine that when practically every country on earth save one (the USA) has killed your people for sport...
...You're happy to receive even 20% of the independent Land promised you.
