I’d have to see a source on that. I had a student whose dad was stationed near HCM Trail and could see it with his naked eyes. Said they could have shot PAVNs all day, but were prohibited from shooting across the border.
” Said they could have shot PAVNs all day, but were prohibited from shooting across the border.”
Very likely. The Trail ran through Laos and Cambodia. If you are going to grant your enemy the freedom to resupply because he will cross a border and you won’t then you aren’t serious about winning the war. LBJ and McNamara weren’t serious about winning. They were content to send GIs into a war without the intention of bringing it to a victory.

Google ‘Operation Barrel Roll’ and ‘Operation Steel Tiger’.
