Tibet is a perfect example of why we should never have a unilateral disarming. Tibet once had a very powerful military. When one of their rules that followed the path of Buddha, they laid down their arms unilaterally. China, then seized the land and the rest is history.
Well if you pull the history so far, I think that all the nations need reflections. Remember the history of local indians or Maoris? not to mention the past wreckage we just want to do better for the present, aren’t we?
