Well, I don't actually mean this is the start of a new era, as I said it is responsibility of the generations to come to decide that. I just compared peace times between wars with this peace period.
In the history, peace wasjust a period between wars. A person with a bussines would have to have war in it's plans at all time. One could never know when a war would start.
In comparison, this peace period, and peace itself now is seen as the normal state of the world and wars at least from my, my classmates' and my friends' point of view are just periods of discord and chaos floating by. Obviously this is not the case, at least not yet, but it is seen like that. What I try to say is that the meaning itself of the word peace has changed from "At the moment we are safe but I don't know about tomorrow" to "This is the way things should be"
Also even if in the past one country was not as war, there will always be some others at war.
Also war was so common before that sometimes, when countries are powerful enogh, there could be several wars going on at the same time. And if not war there will always be some violent incidents going on.
I read about Egypt from the first dynasty to the Sesostris III for now, and all pharaohs always had violence problems in various front's at the same time. At least Bedouins to the north, and Nubians to the south were a problem for every pharaoh and all of them had to send some troops to "Pacify" rebellions. There were also some other problematic tribes and Asians.
So they had several violence problems at the same time.
However, now peace does not mean "My country is in peace with some other" but "The entire planet is in peace". And when a war begins somewhere, we are no longer at peace.
That is something that have never happened before. Periods of whole world peace.
That is not irrelevant at all. That is why I say we are in the most peaceful era ever, because it looks to me that this world peace periods could only be broken by incidents in one country at the same time, meanwhile the rest of the world would just watch horrorised and say "What a terrible thing". It looks like this is going to last a long time.
For me, this is so big of a change that I think it will even grow bigger. That is why I dream about some day when people look back on wars and say "That is no more"
