This difference
"But also fair to presume it might’ve made some difference." is measured in deaths and disability.
You are as much as admitting that to save the book cost the lives of some Americans. Deaths that Woodward could have prevented.
Yes, Trump is responsible for more of those deaths maybe tens of thousands but Woodward's hands are not clean. It is my opinion that his book is not worth one life. This is like a historian filming a dyeing soldier bleeding out from a gunshot when instead of filming the historian could have saved the solider by putting pressure on the wound or applying a tourniquet.
