A world order is not a bad idea. What is bad about it is WHO intends to run it and HOW and what will become of us all if they get their way. So, ending that is the first step to establishing the unity of Mankind. How?
Here's what we do. We end the ruling bloodlines, the malevolent dynasties, the black heart of capitalism. We do this by closing down all the banks and putting on trial all those responsible for them for crimes against humanity. We show due compassion for the level of monstrous stupidity and moral redundancy they embody and have perpetuated for centuries, ie lenient sentencing and no life imprisonments or capital punishment.
Then the governments of the world and the best economic and business brains on the planet evolve a form of intergovernmental working so that each country can begin issuing its own currency and governing its own money supply.
Each country will help its neighbour in this task. Treaties are drawn up to ensure that no vast expenses are henceforth devoted to useless scientific programs, nuclear weapons, germ warfare or any other insanity and all the problems of this earth and the people in it are addressed with total focus.
Free trade, so-called, is finished and legal law currently devoted to ego and egoic pursuits is abolished in favour of humanitarian justice and wisdom.
Disease, poverty, ignorance are tackled unilaterally.
Moral principles that reflect WHO WE REALLY ARE are resurrected and implemented in culture, society and education. In this way, the will of over ninety percent of the people on this planet is implemented in the pursuit of peace and happiness for us all and the myth and idiocy of egoic delinquency masquerading as freedom is laid to rest once and for all and true freedom is born.
Institutionalised religions that divide man from man will cease to exist.
Political ideologies will be unnecessary.
Bloody wars between brothers and sisters will be no more.
No more will a tiny group of delusional greed-driven nutters get to run the destiny of the human race in their own interests and drench the earth in blood in the process.
