Internationalism celebrates global diversity while globalism aims to level it. The near-200 countries of the world today were carved out of treaties signed after conflict, whether localized border disputes or major concerted campaigns at the level of two world wars. After each of those horrific showdowns as technology evolved to the point of annihilation, countries agreed to establish mediation centers to resolve conflicts through discourse instead of armed force. The first failed and led to a new world world. The Second is the United Nations and it operates as a toothless forum rife for corruption because countries are no different than people.
By now it is common knowledge that human babies are totally dependent on others for survival. They know only themselves and their needs. They are nurtured to socialize, to learn which behaviors are acceptable to others and which are not. They learn to moderate emotions, to learn self-control in favor of social gain. The variations in nurture, learning and social acceptance are astronomical. Multiply the single child’s experience by a factor of a hundred gazillion for a hint of how complex is the human dominated planet earth.
Internationalism aims to create bridges at all levels to promote cooperative interaction that promotes the aims, welfare and values of all those involved. The scope of that effort ranges from the personal, social and economic arena to the greater institutional and transnational corporate levels. Like all individual humans, those entities have personalities influenced by historic precedents and modern-day temperaments. Internationalism is an attitude that that they can all all peacefully coexist and mutually prosper.
