One World One Nation.

Strangely I agree with this, though only because it lacked Morgan freeman.

Who do you thinks leading the Marines? *dramatic music, Morgan Freeman steps out of plane*

Everyone look over there its Nelson "God" Mandela leading the marines against the march of the penguins.

I say we send in 50 battalions of soldiers in to murder the bastards, but penguins are the natural predator of light infantry so after the last of them fight to the death we nuke them and run into they're highly populated citys and murder they're wives and children. When we finish we sweep the battlefields and make the survivors fight to the death in a collusium and the remaing 10 get lined up in shot.

The U.S Senate could learn a thing or two from my logic.

BLAH! The vast majority of you disappoint me.
"United Earth? Imposibru!!! bla bla bla..."

Seriously, It's like Globalization doesn't even exist to you people. Hell! I'm not even going get started on the symbolization behind the vary technologies that you guys are using to talk about how "impossible" a united Earth is......

It's not that it is impossible just not likely in our lifetime.

Where in the Universe was the SA armada?! Its your **** homeworld for crying out loud! You defend it to the death or glass it to nothing and blow it to Oblivion, not allow it to fall to Xenos.

On the topic:
Unlikely. Cultures, religions, philosophies, technologies/their use, and even to an extent, genes are influenced by where you are [amoung many, MANY other things]. So there would likely never be a homogeny that could hold together the human race. Even globalization has only so much influence, especially with the tradtionalists and fundamentalists out there. Not to mention the constant divisions of 'race', 'nationality', etc. Even a sweeping conquest probably would never create a united humanity.

If there is ever hostile alien contact, than it is possible, I believe.

You play way to much total war.

if someday earth is united, we would be like the EU but bigger. that's the most realistic option.

To unlikely to happen, unless someone invents mind control.

"One world one nation" sounds like the title of a nickleback song.

* Suicide from name*

I'll bet you one month of you choosing my avatar that they will make a song called somthin extremely simmilar within the next say 6 months.

Fuck it your on, I bet nothing.

Fine, it's not like you will remember the bet anyways.

What bet?

Warhammer 40k Imperium of Man. Think about THAT possibility.

It would be better if it was like We Are the World except with all the shitty radio rock bands.

From what I understand of the Warhammer 40K universe, the IOM as it is is not actually as the Emporer intended it to be. How it is is in fact the result of being in a perpetual state of warfare.
