Just something to think about I personally think that the nations will never be united unless it is under the control of one government. All the different governments are greedy! Humanity will probably destroy itself before this ever happens. Humans are horrible, we slaughter, lie, deceive, manipulate, connive, and cheat. It's not possible for us to get rid of all these qualities instantly. I don't even think it will happen after a few generations. The more powerful a country gets, the more greedy the country will be. No one wants to head backwards. What are some of your opinions?
as long as there are differences in opinions, views, and politics...it will NEVER happen. sad but true.
No, this would never happen. There is a lot of hatred between some nations and I doubt they'd ever cease. And the opinions between the different nations are all different so it'll be hard to convince each and every one of them to think the same. Also there are things such as racism that still exists so the chances of having unity between all nations is close to 0%.
If there is unity under one government it's probably a dictatorship. There is unity on most of the planet at the moment, no world wars in our generation...
