T. Belman. Israel has not agreed to table the extension of sovereignty so they’re not committed to it. So UAE have to rely on Trump’s assurance only. Israel is not even bound to wait for Trump’s approval. She can extend sovereignty before the end of the year without Trump’s approval.
Besides, it is implied that “all things being equal” preceded Trump’s assurance that he would not recognize Israel’s annexation etc.
Notice he didn’t assure them that Israel won’t extend sovereignty for 4 years, only that he wouldn’t recognize it if she did. I am not all all concerned about Trump’s assurance. Things can change.
