Personally, I think it's not too far away. People - especially our children - are being taught to think globally, not nationally, nowadays, to be a 'citizen of the world' rather than of their own countries.
There are lots of pointers. One I thought of the other day was the problem of the 'rogue states' - you know, like North Korea and Iran (to name but a few). These are states which usually are totalitarian and which seem to do what they like to their poor and oppressed people while they have the power. Look at Zimbabwe - it seems that nothing will free those people short of Mugabe's death. What is to be done about states which, though they have the right of self-government (whatever that is to the totalitarians), nevertheless seem to do their own people and the world at large absolutely no good. Some even actively support terrorism and are a real threat to world peace.
The question is, should we all sit around and refuse to do anything about a 'sovereign nation' and just hope that 'the bomb' won't go off, or should we do something about it? Should we put mechanisms in place - in other words, a 'New World Order' - which will, in effect, police it, and ensure that it is so watched over and controlled that no single part of it can ever prove a menace to the welfare of the other inhabitants?
I think, in a nutshell, that is the solution which the politicians of the world actually have to such very real and threatening problems as these. We may not like the solutions, but we do not like the problems, either, so, for some people, it's going to have to be.
Again, my thoughts are that we would be paying a terrible price in order to live in what 'they' would say is 'peace and security'. Now, the politicians have in it for them an enhanced 'gravy train' and power (and so have the rest of the hangers-on) as I see it, but the 'little fella on the street' would, in effect, be promised freedom but actually be in bondage. And, let's not ever think that 'the big guys' would ever cop for having to pay for their misdemeanours in the same way that we would. No, no, there would still be one law for the rich, famous and mighty and another for the rest!
Yes, the flaw with the whole thing is the flawed humanity of man. However, man having thrown out God in this godless world, in effect makes a god of himself, so he cannot consider that he is unable, or unworthy, to do anything he pleases.
A major pointer to the one world rule is the spread of information and control. It's amazing what a computer can do to store vaste amounts of information on every single person on the planet - it's literally possible (even though they couldn't find one ship that'd gone awol recently!). Did you know that microchipping humans is gradually gaining acceptance?
Interesting, how history repeats itself, as they say. For, in all these milennia, there are still tyrants, there are still mass murderers, there is still mass human suffering caused by evil persons, wars, violence and death. Not much has changed, in spite of our higher developed state - once one rogue dies out, another pops up in his place and the misery continues and every now and then a war develops over it. Same old pattern, also proving that man learns nothing from history, for he continually repeats the same errors.
No doubt we shall all be told this, just before the unveiling of the 'great plan' that one world rule will end this sad trajectory of history and reverse all man's ills. Don't believe it. For history shows, again, that before all of these things ever came on man, there was always one great orator, one superman, who was going to end it all and bring us all into a new and beautiful super age of guaranteed peace, prosperity and model citizenship. It starts with the propaganda.
Are we close? Yes, I think so, for the propaganda is here, the technology is here, as well as the will to do it - it only awaits the great orator to draw everything together.
