Drop a pallet of cash like jugears sent to Iran about 50 miles behind the caravan and watch it literally explode in every direction– inform the invaders that they need to turn around to stake their claim to millions of dollars of "aid" – Trump is a hero for helping the people– we get to remind the NPC's about what jugears did if they object and the mob turns around and probably destroys each other in the ensuing chaos and mayhem– sell it on pay per view and your problem is solved– no way they reorganize in time for the elections
