First point, I don't subscribe to the 'evil yanks' philosophy.And why you ask was Laos being Bombed?
because the North Vietnamese were violating the neutrality treaties to move supplies south using Laos as a staging and transit area like Cambodia
Of course the genocide of the Hmong continued
But those evil yanks eh?
Second, I fully understand that the Ho Chi Min trail went through Laos and Cambodia and was therefore a valid target, militarily. But the bombing was poorly targeted and not as effective as it could have been.
The Hmong were used, misused and abused, ultimately being well and truly sold down the river. No different to Laos as a whole (and Cambodia). Those countries went down 'click, click, click', just like the dominoes they weren't supposed to be.
All viewed, of course, through the prism of 2019 and a host of eBooks so readily sourced.
