Do you know why the world is more peaceful now? In the past, all the power was consolidated to the king and the king can do anything they wants to. But now in a democratic country, you can not do that so easily. Also, nuclear power gives some balance to the world power and that is why North Korea can threaten the USA but fear to do any military conflict. In the past biggest and more trained army win the battle but now one single nuclear strike could turn the tide no matter what's your army size is. The nuclear weapon is the most dangerous weapon in the human's arsenal and this is the reason we haven't seen any world war till now. World leaders understand mind your own business is good for everybody.
Yep, that's what happen in our world right now.
No conflict? only enough to eliminate the nature of lust and greed that exist in humans. Unfortunately, the world is designed to balance Yin and Yang, however, we live in a world full of question marks, between yes and no. So if ideally, harmony occurs, the first to second world wars will not be created and will not cause an economic crisis anywhere. The greed of mankind has made the world unbalanced.
In history only us, the human species has killed each other more than any other species.
Because we are at the top one of the food chain, there is no enemy who can challange us more than our own species.
We struggle to dominate each other, kill others if they think it's necessary
Who knows in the future maybe another species will come to earth and dominate us so that circumstances will bring us together as
one
