Nobody wants to watch a movie where Thanos wins. Nobody wants to be left with a feeling of "now what"? Even the beginning of End Game started out by leaving viewers with an empty feeling until much later when a solution was discovered. A long shot? Yes, but they took it.
Keep watching the movie(s). There are multiple. Don't have cherished outcomes. Allow God to play things out the way God wants to (even if Trump is no longer part of the picture by the time the movie(s) come to an end).
To add, Trump mentioned in his speech that most people don't quite feel the full effect of what is actually happening to our nation. Many are blatantly aware of the precipice, and some even feel as though we've already gone over the ledge.
But far too many still have no idea. Perhaps some day, "The Plan" will need to move forward regardless of whether or not everyone is awake. "The Plan" will have no effect if it does not take effect until there is nothing left to salvage.
(Edit: Right afterward, he mentioned that things would be much worse by 2024, but that the voting would also be much different by then as well)
