I'm fascinated by what you stated. I'd like to know more, especially the part about warnings before bombings. Could you give me a source? Thanks.
If you have the option, there is actually a good documentary on Amazon Prime Video channel, called Thud Pilots, its about F-105 bombers in Vietnam. Its pretty good, and even a few of them talk about ridiculous rules of engagement and target selection, plus warnings given to the enemy that made missions much more dangerous and less worthwhile.
