Hopefully, he will not be captured alive.
Ideally, he would be tried and convicted and end up at the end of a rope, like Lord Haw Haw. But that's unlikely these days. Smart bombs are so much more effective, and so much less tedious, than Judge Leonie Brinkema and the twelve dumbest of greater Alexandria, VA.
I'm sure "Azzam the American" would agree with Haw Haw's last words before they dropped him through the floor, on 3 January 1946: "In death as in life, I defy the Jews who caused this last war, and I defy the powers of darkness which they represent".
That was an interesting read about Lord Haw Haw. Don't think it would end up that way today. After all the BBC and NYT have been getting away with it for sometime.
That was so interesting and clearly informative, Time magazine had a chart of the (very few) historic treason trials.
