World Peace vs Time

That's actually better than I thought it would be.

I don't think thats too bad... It shows we really do have emotion, our pwn thoughts and opinions, and how we operate when two different opinions clash. (Its also human nature)

Wasn't that just Rome though ?
And could they explain peace ? Peace as in everyone is content or that there is just no war ?

Well, in some other corner there were people waging war. The world was never at peace, never will be.

Was that when plague wiped out a good chunk of the human race?

Now, how can we blame the US for all the trouble prior to the 1700's?
