It’s always fascinating when you have an intersection of religion and geography. As a practical matter, anyone’s Promised Land did not come about from God making it happen, but from your side killing all the people who were there before you - and/or killing enough until you drove the rest of them out. The Old Testament is pretty clear that the children of Israel committed genocide on the people who were there to get their Promised Land.(God’s command that every living person in Canaan be put to death). It’s also clear since the crusades that people who are not Jews have been declaring it their land, and killing the people who were living there at any given time, no matter what their religion.
So how much validity to we give a claim that this is my sacred God given land? I’m often reminded of the Lakota Sioux and the Sacred Black Hills that the white man stole. In a lot of ways that claim is a whole lot of bullshit. The land used to belong to the Cheyenne, before the Lakota were driven out of the great lakes area and pushed west. The Cheyenne also fucked up by introducing horses to the Lakota, who eventually became so numerous that they drove the Cheyenne out of the Black Hills. IOW, the sacred Black Hills of the Sioux we’re only the sacred Black Hills from about 1775 on.
That said, once you claim some places your sacred land, then it is hell to pay if somebody else comes along and drove you outta there the same way you drove out the previous inhabitants. I have no idea where the hell I’m going with this, but I just had a thought bubble about the factor of the land belonging to someone because their religion said it does.
When the smoke clears, you have the military juice to keep it or you don’t. Whether you attribute your successful military operations that took it in the first place to God or not, well, that is another matter for another day’s discussion.
