And do you know what a straw man is? The reason I ignored suggestion of the wife being executed in my response is likely the same reason that the author's assertion was cut from the piece. Its based on one source referencing exactly one individual. This not only substantially increases the probability of this being a lie (consider: traitorous spies have, by definition, already shown an interest in hurting their nation and the people of it for money, and are willing to lie, cheat, and steal to achieve that end), but provides 0 information on what happened and why - which leaves the reader, you in this case, left to fill in the gaps with the most heinous story imaginable.
You were implicitly stating you oppose the execution of spies. And that is certainly your right. At the same time, I think many people do not consider what traitorous spies actually are and do. I'm also generally against the death penalty, but not unconditionally - traitorous espionage would certainly be near the top of the shortlist of things that I think fully justify execution.
Are you saying it is fine to execute relatives of spies?
