Dunno about deserting to join the Ukrainian army but they seem ok with leaving the US military and joining the Ukrainian army. See Malcolm Nance for example.
I had heard of the blacklist, but thought that it was for those who deserted the Irish military to join the British. Punishing deserters is understandable, no matter the motive.
That said, if I understand the article correctly, those who did this were punished worse than deserters who did not go fight?!?
I understand Gemini created the code itself, but did it also write the text?
