Julius and Ethel Rosenberg were executed to set an example, like the unfortunate duo Sacco and Vanzetti, who were also seated in Thomas Edison's Rocking Chair at Sing-Sing decades earlier.

Spies, civilian or military, must never be executed because they have information in their heads they can reveal to CI agents at a later date. We cannot interrogate a corpse.

Spies, civilian or military, can also be traded, if they were valuable.

Iranians who spied for Israel over the past two years were simply executed. The Mossad did not seek to trade for them, as Tel Aviv saw them as disposable assets ("useful idiots"). And the Iranian regime saw this and so made examples of them, rather than incarcerate them for future interrogations or trades.

"FUNNY 2"

The crime of "treason" is the most difficult case to prosecute in the US because this crime is only applicable during a Congressionally-declared state of war. Moreover, there must be at least two eyewitnesses to the alleged crime that can testify in court.

Today, prosecutors and pundits throw around the words "treasonous" or "traitor" more as descriptives, rather than legal code.

When the UK faced legal difficulties prosecuting Brits who were supporting the Nazi cause, the culprits didn't commit treason per se under UK law, so their parliament enacted the Treachery Act (1940), which covered their offenses.

The Treachery Act is something the US deperately needs, because that would have covered Dummkopf Trumpf's treacherous activities with the Russians, Israelis, oligarchs, Jeffrey Epstein/Ghislaine Mawxell etc.
