Humpty Dumpty isn’t about an egg that falls off a wall. It’s a metaphorical prophecy. Humpty dumpty is President Trump. The Wall is the very foundation on which he created his politcal campaign. But he falls off the wall. The fall may be a metaphor for his presidency failing, whether through impeachment or invasion. The kings horses and all the kings men, could be the american people trying to encourage him to continue, but if impeached he could not. If through war/invasion he probably lost too much and is broken.
