The roots of a country are no different than your personal roots. Where you came from. What your family was like. Traumas you experienced and so forth.
All of these historical antecedents though not entirely fatalistic, do create certain dispositions and tendencies that without awareness and attention, can seem very fatalistic.
If a country acts perpetually violent, look to its roots and you will find violence there. If you are violent, look to your roots, and you will find violence there in some form.
How to transform the roots? How do we fundamentally transform violence?
In the case of a country, that could mean starting over. Digging out. Discarding. Doing it again.
But, without a transformation in you — the people — this more externally-oriented strategy will create the same violent situation all over again in time.
The answer is: you have to solve violence inside of yourself in order for a larger matrix (like a country) to be less violent.
The more violence we see in the world, the more we need to turn within and eradicate the seeds of our own violence. And, it's more the emotional/psychological kind, of which the physical kind has its roots.
It happens in the most mundane of situations too. With your spouse. Your child. Your neighbor. Your co-worker. And most of all, the relationship with your Self.
Turn a blind eye to violence without as it is just a mirror of violence within, and then do your work.
