A single sourced "news story" by anyone, is a non-starter. It isn't a news story, it is hearsay. First hand testimony with fanfic levels of correlating data have caused untold misery throughout History, of late being a particular sorry swing of that pendulum.
When someone like Hersh is behind it, I expect _WAY_ more. His single source could be President Biden on the record and I'd still take issue with this.
All of this could turn out to be nearly 100% correct and it would still be irresponsible. The implications of getting this even slightly wrong are potentially catastrophic, in so many unpredictable ways.
Perhaps I'm showing my age, but I grew up learning not to F around with the implications of a land war in Europe.
