As social animals we need friends, but we make friends on the basis of trust, which comes about as a result of affection and concern for others. You can’t buy trust or acquire it by use of force. Its source is warm-heartedness.
Peace in the world depends on peace within. If we have that we can approach problems in a spirit of compassion, dialogue and respect for the rights of others—always a better solution than resorting to a use of weapons and force. External disarmament depends on inner disarmament.
