[MENTION=17829]Roboartist[/MENTION], think of where the Human race would be technologically if all the World's Countries spent just ONE YEAR's' "Defense" budget on science and bettering Humankind. To put that in perspective for those who may not fully understand it, NASA's yearly budget is what, just over 1 million while the USA spends anywhere between $650-800 BILLION (that is made public) on "Defense". I'd wager that number is actually closer to just over 1 Trillion/yr if you account for all the Black Ops, backroom deals, etc that go on.
The Human Race is being held back by petty squabbling over Land, skin color, Religious views, and Natural Resources (that we don't even need to be reliant on). Hell we might even have been exploring the entirety of our on Solar System (manned) by now as well as having well established colonies on Mars and 1 or more of the Moons of Saturn if it weren't for Human greed.
