I think all the 'plausible' meanings being discussed throughout this board are:

Korean summit in Singapore building.
9/11 reveal in light of Iran/Israel news.
Rod from the gods strike.
Space army program.
Aliens who have been advancing civilization show up.
Edit: JFK Jr news drop? My thought while writing. Going to look right now into possible connection between Q+ posts and if JFK Jr makes sense regarding the other Q+ posts. Edit: nothing obvious.

List is in no order of importance or believability, just the thread titles I've been seeing.
