Would you be less frightened if the UAE opened up an Embassy in Tel Aviv?
How about they also have Israel open up an embassy in UAE, and they enter into a formal agreement recognizing their right to exist.
Yes, that would go a long way.
With all due respect, I think labelling people who have concerns about this deal as "frightened" diminishes them and belittes their argument. Many people who don't applaud this deal are rational people who care about their country.
