So similar to like NATO?
common currency doesn't sound likely though, but free trade zone, council for co-operation and a task force for protecting trade routes and terrorism does sound plausible
NATO is an offensive military alliance. What I envisage is nothing more than an economic community, more akin to the EU. As more and more countries sign FTAs of various kinds, why not join a grand economic union?
If we think about the nature of the state. It is nothing more than an economic, political and military complex. Since people prefer economic integration, simply implement economic integration.
As for military and political affairs, they are also governed regionally within a state.
The government of my city cannot run the public affairs of the city next door. Cops in my city don't go to other cities to fight crime most of the time.
If we extend this pattern to countries, you'll see that it doesn't change the way countries work. It just adds a mechanism for international coordination.
An organization often has a theme. The theme of the UN is to mediate conflict and avoid war, not to co-operate. What we need now is economic cooperation, and we should set up an organization whose theme is economic cooperation. And all rules should be formulated with the aim of promoting economic cooperation.
So I'm envisioning a united army and police whose job is simply to protect trade and maintain economic order. They should not take on the task of antagonizing other countries, promoting ideology, etc.
Because there will always be local protectionism, corruption, deterioration of security, transnational crime. The alliance needs force to deal with these problems. Because there are common principles that countries should respect when they join the Union. These principles should be basic and vague. But there will always be those who will try to renege, and when the rules cannot be fairly enforced, the alliance will automatically collapse. That's why we need coercive powers.
