And I used to wonder, what sort of primitive mentality allowed the endless, mindless mutual slaughter that went on for so long in the trenches of Europe during WWI.
Eureka!
PI 1984,
I believe it comes from having leaders on both sides that are either away from, and/or immune to, the stress of battle and that believe they are "just that close to victory". They use their "flags" to rally the troops, and keep them fighting.
There have not been enough conclusive victories to lead the other side to believe all is lost. And when there is, the other side will feel no need to give an inch and will collect it's vengeance. Then, after the battle is gone and we are left with the aftermath, will we see the cost.
