The effect of one good-hearted person is incalculable.

For ages the world has been living by the stupidity of an old Roman adage that says if you want peace, prepare for war. As if anything said in ancient times must be wise, people have used this phrase to justify some of the most unjustifiable arms build-ups, which, far from creating peace, has only become a self-fulfilling prophecy.

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.

I am not a pacifist, however I do believe that the U.S. tends to resort to force too quickly. I am not referring only to the current administration; the same thing happened in the Balkans, and on other occasions.

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.

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.

It is essential that justice be done, and it is equally vital that justice not be confused with revenge, for the two are wholly different.
