Crate em up and ship em on back to that shitehole they crawled out of...one-way ticket with severe consequences for an attempted return.
Any bets that the bulk of that (99-percent) will never be recovered?
and then execute them and dump them overboard once well beyond the international waters border...
No, crate them up and while the C-141 Starlifter is over the middle of the ocean ROLL THEM OUT THE BACK RAMP W/O Parachutes.
