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.

I am constantly challenged by pessimists who insist that military solutions are the only way to go. This was true in the 1980s, and it is true today. You should know that I do not consider myself a pacifist; there are times, in my view, when military action may be necessary.

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.

War, and the preparation for war, are the two greatest obstacles to human progress, fostering a vicious cycle of arms buildups, violence and poverty.

Peace is not a dream; it is hard work, and there is nothing naive, glamorous or simplistic about it.

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.

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.
