This would all make sense, except for the little fact that the land being "promised to Jews" had very little to do with the reason why Jews in the 19th century sought a homeland of their own.
It had much more to do with the facts of persecution in Europe and fear for their lives (which proved to be a very justified fear).
Using your analogy would mean that any nation that seeks to have a homeland (whether it is Palestinians, Tibetans, Kurds, or Jews) should not worry about the poor
physical conditions and "real estate" in which their people live in
reality, but rather seek "inner peace" in their heart and have a homeland in their imaginary world.
The reason why Israel still has to fight for its existence is purely geopolitical. What you have in the Middle East is vestiges of Islamic Imperialism (that, incidentally also seek to have control over "real estate"), that for over 1300 years had control over territories, and now they feel "disrespect" because someone else lays claims to the same land they once had. That's not a simple situation, to say the least.
If Jews were to "change their perspective," in whichever way you see fit, that would still not change the geopolitics in the Middle East one bit.
