rabbi, a genuine Torah question, and i am asking it honestly because the slogans on both sides do not help. what does halacha actually say about eretz yisrael and the non jews living there?

1. the claim. the Torah gives eretz yisrael to the jewish people, that is clear from breishis on. but does that promise work like a property deed in halacha, meaning individual jews have a halachic right to specific land that individual non jews live on today, or is it a national destiny that does not translate into dinei mamonos between people?
2. kibbush then and now. in the times of yehoshua and the melachim there was a mitzvah of kibbush ha’aretz under specific conditions. does that mitzvah apply today, with no nevuah and no melech? and did the rambam even count it in the taryag?
3. the people living there. whatever the answer on sovereignty, what does halacha demand toward the non jews actually living on the land, their property, their homes, their dignity? gezel applies to the property of a non jew too, so how does any claim of yishuv ha’aretz sit next to that?
4. dina d’malchusa. does the modern state and its courts count as a malchus for these questions, and does that change anything halachically about land sales, disputes, and building?
5. what does the Torah want. leaving politics aside, what is the Torah’s own expectation for how a jew living in eretz yisrael should think about this: justice, shalom, yishuv, or none of the above?

i am not looking for a political answer, i am looking for the halachic one.
