War is like a fire in the human community, one whose fuel is living beings. I find this analogy especially appropriate and useful. Modern warfare is waged primarily with different forms of fire, but we are so conditioned to see it as thrilling that we talk about this or that marvelous weapon as a remarkable piece of technology without remembering that, if it is actually used, it will burn living people. War also strongly resembles a fire in the way it spreads. If one area gets weak, the commanding officer sends in reinforcements. This is throwing live people onto a fire. But because we have been brainwashed to think this way, we do not consider the suffering of individual soldiers. No soldiers want to be wounded or die. None of his loved ones wants any harm to come to him. If one soldier is killed, or maimed for life, at least another five or ten people - his relatives and friends - suffer as well. We should all be horrified by the extent of this tragedy, but we are too confused.
Frankly as a child, I too was attracted to the military. Their uniform looked so smart and beautiful. But that is exactly how the seduction begins. Children start playing games that will one day lead them in trouble. There are plenty of exciting games to play and costumes to wear other than those based on the killing of human beings. Again, if we as adults were not so fascinated by war, we would clearly see that to allow our children to become habituated to war games is extremely unfortunate. Some former soldiers have told me that when they shot their first person they felt uncomfortable but as they continued to kill it began to feel quite normal. In time, we can get used to anything.
It is not only during times of war that military establishments are destructive. By their very design, they are the single greatest violators of human rights, and it is the soldiers themselves who suffer most consistently from their abuse. After the officer in charge has given beautiful explanations about the importance of the army, its discipline and the need to conquer the enemy, the rights of the great mass of soldiers are almost entirely taken away. They are then compelled to forfeit their individual will, and, in the end, to sacrifice their lives. Moreover, once an army has become a powerful force, there is every risk that it will destroy the happiness of its own country.
There are people with destructive intentions in every society, and the temptation to gain command over an organization capable of fulfilling their desires can become overwhelming. But no matter how malevolent or evil are the many murderous dictators who can currently oppress their nations and cause international problems, it is obvious that they cannot harm others or destroy countless human lives if they don't have a military organization accepted and condoned by society. As long as there are powerful armies there will always be danger of dictatorship. If we really believe dictatorship to be a despicable and destructive form of government, then we must recognize that the existence of a powerful military establishment is one of its main causes.
Militarism is also very expensive. Pursuing peace through military strength places a tremendously wasteful burden on society. Governments spend vast sums on increasingly intricate weapons when, in fact, nobody really wants to use them. Not only money but also valuable energy and human intelligence are squandered, while all that increases is fear.
I want to make it clear, however, that although I am deeply opposed to war, I am not advocating appeasement. It is often necessary to take a strong stand to counter unjust aggression. For instance, it is plain to all of us that the Second World War was entirely justified. It "saved civilization" from the tyranny of Nazi Germany, as Winston Churchill so aptly put it. In my view, the Korean War was also just, since it gave South Korea the chance of gradually developing democracy. But we can only judge whether or not a conflict was vindicated on moral grounds with hindsight. For example, we can now see that during the Cold War, the principle of nuclear deterrence had a certain value. Nevertheless, it is very difficult to assess all such matters with any degree of accuracy. War is violence and violence is unpredictable. Therefore, it is better to avoid it if possible, and never to presume that we know beforehand whether the outcome of a particular war will be beneficial or not.
For instance, in the case of the Cold War, though deterrence may have helped promote stability, it did not create genuine peace. The last forty years in Europe have seen merely the absence of war, which has not been real peace but a facsimile founded fear. At best, building arms to maintain peace serves only as a temporary measure. As long as adversaries do not trust each other, any number of factors can upset the balance of power. Lasting peace can only assuredly be secured on the basis of genuine trust."
