Yes pacifism - but more essential
The original conflict causing the situation needs to be solved immediately, that's a questionmark I am uncertain of, but I can imagine US have to find out if they're asked to. If they proove them self worthy to solve it with reason then the world might forgive them to a certain level.
The ideology is a bit harder issue. How can a country reengineer itself when it has locked itself in this position? No way?
My ideology is based on end all dissent forever trough complete understanding between individuals. A full extermination of all hate by a technique to absorb and consume it instead of retaliating as well as preventing it to be generated by misunderstandment. There has to be a world wide agreement to educate this to people and I guess that it's going to spread if not as fast as a wildfire because of popularity. Under this, the world has to act as a single mass, so it needs to be exposed to this new ideology for a while, probably continous massmedia would do.
Once my ideology is fully established, the people living under the ideology of freedom can live in peace, as well as all any other nations. What do you do with resources spent on military? Well? What about education instead? What about resources in general? They're running out sooner or later, if the world is united, won't it be eaisier to come to an agreement on how to share them as well as plan a new future instead of looking into our current hopeless?
I didn't go into detail, I noticed, I just listed up the most essential results... I guess some could go on for ages into how this would revolutionize the world but I'm too tired for that.
What do you think?
