My country is a country of teachers. It is therefore a country of peace. We discuss our successes and failures in complete freedom. Because our country is a country of teachers, we closed the army camps, and our children go about with books under their arms, not with rifles on their shoulders. We believe in dialogue, in agreement, in reaching a consensus.

The problem with basing weapons sales on strategic interest is that these interests tend to shift over time, while weapons are durable goods that do not evaporate as quickly as some alliances do. Once supplied, they can't be taken back. That leads to situations such as the ones we have seen in Iraq, Somalia.

Peace is a never-ending process, the work of many decisions by many people in many countries. It is an attitude, a way of life, a way of solving problems and resolving conflicts. It cannot be forced on the smallest nation or enforced by the largest. It cannot ignore our differences or overlook our common interests. It requires us to work and live together.

We are calling on countries that supply weapons to comply with certain restrictions: not to sell weapons to human rights abusers, not to sell them to governments or groups carrying out aggression against states, not to make weapons sales that could disrupt security or development in the receiving region. These are in many ways common sense principles, but sadly, there seems to be very little common sense in the international arms trade.

I would like to see the U.S. fighting another war, perhaps in addition to that against terror: a war on poverty, illiteracy, disease and environmental degradation. It is certainly within the power of your country to act on all of these fronts, but, unfortunately, your leaders have become obsessed with a single issue.

I have to believe in the possibility of peace, because the alternative is to accept the inevitability of continual war, and of always living in fear. It doesn't have to be that way. However, there are no simple solutions, and I am not the possessor of a magic formula for peace. All I can say is that for peace to succeed it requires perseverance, patience, humility, compromise, and commitment, from all parties.

Peace consists, very largely, in the fact of desiring it with all one's soul. The inhabitants of my small country, Costa Rica, have realized those words by Erasmus. Mine is an unarmed people, whose children have never seen a fighter or a tank or a warship.
