Hereโs how I know that The Falcon and the Winter Soldier is fictional...
How they were talking about the world coming together after the snap. Life being better and such. Living through 2020 says no, absolutely not.
There would be a few months of commercials of โweโre all in this togetherโ and โin these trying times...โ
But most likely (at least in the US), back to business as usual... I can even imagine some people saying the whole thing was a hoax and that the people snapped were a part of a vast conspiracy to take away guns or something... while the rest of the people are just trying to survive.
