We do not implicitly trust anyone or anything. Some of us have learned, through sad experience, that we cannot even trust ourselves. We live in a world of distrust. Individual distrusts individual. Group distrusts group.
Nation distrusts nation.
This situation is more than tragic, since peace of mind can come only when an absence of distrust actually exists. When confidence possesses the human heart, tranquility reigns. Joy and happiness begin. All past history would seem to indicate that this is so. Mere human speculation here only serves to add greater confusion.
