What is the word or phrase opposite in meaning to fait accompli. For your reference the meaning is given below. I would prefer a foreign word but any can do.
French fɛt akɔ̃pli/
a thing that has already happened or been decided before those affected hear about it, leaving them with no option but to accept it. "the results were presented to shareholders as a fait accompli"
I want the word to be used in a particular context for instance an event that many people are glad has happened, many wish a different event to replace it. Like an event in the past that has bittersweet memories associated with it.
