Dear Trad,
I appreciate what you are saying.  But, name for me one nation in history that has been able, no matter how powerful, to remain King of the Hill for more than a few centuries.  Someone more powerful eventually appears and takes over only to eventually be overthrown by another more powerful.   The problem is that we have reached the point where that power has grown of great that it could literally destroy the world.  Yes, lets engage in an experiment.  Let's really attempt to follow Christ and love one another as we are loved by God.  To treat every man, woman and child as family and do all we can to insure each person has access to whatever he or she needs to live with the dignity of a child of God.  May take a while to catch on and we can always hold on to our weapons until it is safe not to, but the world will never be save as long as we have them.  When we learn to treat others as we would be treated perhaps, just perhaps, we will find peace.
