Generating an atmosphere of peace is usually a gradual process. Even after you have expressed the desire for peace, you may not instantly arrive at that place of peace until you begin to build trust. No one will sign a peace agreement if they know that at any moment, when they are least prepared and preoccupied with other matters, you are likely to deal another blow to them, betraying their trust. Peace is built on a foundation of trust, without which there can be no genuine, long-term peace.
Prior to seeking a peace accord, consider and detail with absolute honesty all the issues that might cause you to violate the agreement, or that make you distrustful of your opponent's commitment to peace. Openly communicate these issues as part of the negotiation process. Any such issues and concerns that are not openly and honestly communicated will gradually erode the foundation for the agreement. This erosive energy will create an underlying fault line that results in a sinkhole by which any agreement reached eventually will be devoured.
