10. This reconciliation will only be possible if the various religions, governments and the international community sincerely and actively opt for a "culture of peace", so that there is no more resort to arms in order to solve problems and there is an end to the growth of the arms industry and the sale of arms, etc. (cf. ibid., n. 4; See also the Holy Father's letter to the Bishops of El Salvador, L'Osservatore Romano English edition, 6 September 1982, 7). The local Churches have an active role to play, notably through their messages of forgiveness and reconciliation (see in particular the Lenten Message of the Catholic Bishops of Rwanda 1992; their Pastoral Letters for Advent 1993 and Lent 1993; their Christmas and New Year Messages to Christians in 1994 and 1995; documents published in the Holy See's Report to CERD, CERD/C/338/Add. 11 [26 May 2000], pp. 79-86), but even more through their action on the ground. It is the task of governments and world or regional organizations to put in place solid structures "capable of withstanding the uncertainties of politics, thus guaranteeing to everyone freedom and security in every circumstance". (Message for World Day of Peace 1997, n. 4). All forms of mediation therefore should be encouraged. Existing structures must also be strengthened. In particular, the United Nations, which has done much in the area of maintaining and restoring peace, should benefit from means better adapted to the new missions entrusted to it. Yet structures and processes will not be enough to build a lasting peace, only the path of forgiveness will make this possible.
