The solution is super simple. Have B-52 bomber jets at the nearest air base filling up with these illegals then fly them to southern most end of Mexico and drop them off regardless of where they are from. If they came over the Mexican border it’s the Mexican’s problem; not ours.
Those B-52’s can probably hold 4-500 people easy. A few trips a day until all the beds are empty and fast track all those waiting for a court date then just start more flights as needed.
All illegals must go home. This is not an option. A promise was made to build the wall and secure the border. Hire and fire whomever it takes to get the job done. This was always a problem with political will; not a physical one.
The best part of your solution is that the planes do not land!!! We can rest assured that those particular invaders will never be repeat offenders!!
