At least one analysis responds to this question by saying that the culture of peace cannot be established with states, because the states have become themselves the culture of war. Here is the argument.
“The state devotes its resources and is more or less controlled, overtly or covertly, by the military throughout the world. This is not new but has been true throughout history.
“Let us begin with the Great Powers. The United States, which we may more appropriately refer to as the “American empire” devotes more than half of its national budget to the military and now maintains hundreds of military bases throughout the world. Countries without an American military base are exceptional. Now we learn that almost every African country has one. A Nobel peace laureate, Barak Obama, aided in this expansion.
“Where is the ultimate power in China if it is not with the Red Army?
“Not one of the world’s nuclear powers, the U.S., Britain, France, China, Russia, Israel, India, Pakistan and North Korea, took part in the negotiations at the United Nations for nuclear disarmament.
“Should we have been surprised when the Arab Spring was cut short by a military coup in Egypt?
“At one time it was believed that believed that peace could be obtained by converting the state from capitalism to socialism. And indeed, in the 20th Century, we saw many examples where capitalist states were indeed overthrown by socialist revolutions. But what ensued was not peace. What ensured was a socialist culture of war instead of a capitalist culture of war.
“And we can see why socialism has failed. A socialist culture of war will alway lose in competition with a capitalist culture of war. Socialists tend to share wealth with their client states, while capitalists exploit their client states. In the long run, it is the capitalist states that win the economic competition. The socialist states must either submit (as was the case of the USSR) or become capitalist (as in the case of China).
“If socialism is to succeed it cannot be based on the state. If peace is to be obtained, it cannot be based on the state.”
