I think that people find it easier to distrust others and their intentions than to belief others mean them no harm and do not desire to deprive them of what they have and value.
To live in peace means to not insist on having control over what others do or might do.
When we insist on guarding against what others could or might do to us, however unlikely, then we build, accumulate and maintain the instruments and organizational structures of war.
We remain constantly vigilant to any and all possible threats from others and even make war to preempt such possibilities even when there is no factual basis to the perceived threat.
When we live with the constant expectation that others want to take away what we have, we structure our economies to invest huge proportions of our GNP to preparing for war.
We then fear the economic impact of giving up war as a major industry.
It comes down to what we really want and what we are prepared to do to live with peace and in peace instead of being at war or in constant preparation for war.
It takes more courage and determination to wage peace. Are you up to the challenge of it? Will you support it? Will you do want it takes? Will you help lead the way?
If you say no to any of these, then what are you supporting?
