Ignition Override, contray to the view of what floats to the top, you are fortunate enough to have enough good people who care and who get the job done when the need arises.
I was looking back at the Vietam War. It didn't impinge on my 'radar' until 1964/5 when we were operating nearby but I dscovered that the first US person to be killed was in 1957.
I had been aware of French Indo-China but again Dien Bien Phu was below my radar at that time.
Maybe the problem there was that the conflict lasted for almost 30 years which gave ample scope for 2 or more generations (French and US) to have a meddle with running the war.
In that case, thankfully, our PM kept us out.
