I am a local constituent. I have read of the very high suicide rates amongst returning veterans. I have witnessed PTSD with a neighbour's son-inlaw after deployment and my uncle after WW II and have this to say.
In Lt. Col. Dave Grossman book called "On Killing", shows that only 2-3 % will fire their weapons willing against an enemy without thought. 10-12% will follow suit under duress, but 85% will not naturally use their weapons against another human being.
Governments pursue policy leading to war but fail to recognise as a direct consequence of their policy the great trauma inflicted on the combatants and the enemy as well.
All wars are bankers wars, to control another's resources and balance the National debt. The war on terror was for oil resources, nothing more.
We need a royal commission to hold those responsible for initiating wars to account and equally important to respond adequately to our returning combatants.
