this is the spy game
we tell our people that we will do everything in our power to get them released if they get caught, or else no one would volunteer
We also tell the world we will do everything in our power to never release one’s we catch, in order to discourage spying on us
Israel is just doing the same on their side.
That said, Pollard was not an Israeli citizen spying for lofty goals, he was a traitor for money- so they know we will not release him EVER so they can publicly display their wish for his release, knowing it will never happen
Anyone who knows the spy game knows that we exchange spies all the time, including citizens.
