Joshua 21:43-45 is used by many to show that God has fulfilled His land promises for the nation of Israel and thus nothing else prophetically should be expected regarding this.
I wrote presented a paper at the national ETS convention on this. For those who want to read it, it is available as a free PDF download.

Just a note of warning: for those who have read the Glory Books, this is written as an academic paper (which is not my heart’s delight, but is the required format).
Hope this blesses.
