And it can't just be one nation that does all the work. We as a planet need to finally accept, that humanity has to cut the bull, and finally grow up as a species
The problem with this though is that other species of ourselves haven't even gone through half the increase in knowledge and technology than the ones that would proclaim everyone needs to be the same.
Instead of making wars, we should be "teaching" our pasts, those that are more advanced than other races, not trying to use them to bend to our own wills and principles. You think those people in Iraq, Afganistan and other 3rd world countries even understand what democracy really is?
You can't change a species overnight, going to take 100's more years, before there's a united species, with one goal, one god and one government. Even if a country stormed across the whole globe, today, one fell swoop, it would still take hundreds of years to bring all the countries into conformity. There will always be insurgents, those that always disagree with single rule, single control.
To me that's what makes the world great, separated as it is, because with a separated world I have choices about where I want to go, where I might want to live. With a controlled world, there's no longer a place to escape to, a place for change, because it's controlled by the "one".
I look at it like this, at one time the societies and civilizations were like a giant vortex with mankind at the top and outer regions of it, as time and civilization swirled around and inside this vortex they have slowly been pulled to the bottom of it, the smallest narrow portion of it. I sort of like the vastness of the gaping portion of the vortex, than the narrowness of the bottom of it where everything is compact and controlled.
