I agree....dropping leaflets might help. Drop them right on any caravan now on the move.
I think it would help if Trump administration started using the LIFO (last in, first out) method of processing the invaders. As soon as they step foot on our soil, they are fast tracked through the system and sent home. I know there is a huge back log of these cases, but I think that it is more important to put a stop to this invasion first. If these people find themselves, within a week or so after setting foot on our soil and spending the entire time here in not very comfortable confinement, on a non-stop flight to the southern-most edge of Mexico or wherever they came from, the message would get out to the rest of the invaders it might not be worth spending the time and money to come here. When the invasion slows down, and the wall is built, then the full and close attention can be given to sending the rest of them home.
