It's time to ask why we all in the world can't just work together? Exchange all

East or west it's time to ask why can't we all just work together?
Without issues without fight and without diversion?
We become so divided and all those wars and crisis takes a lot more money and resources then they are worthed.
So If one country have raw material can set the fair trade with other country.
We all have different talents skills by exchanging them we get perfect balance....are our leaders never think about it ?
All the nations are different and unique with strenght and weakness some nations do something good what others don't.
What is the issue that we all have to fight ? Instead of cooperation and harmony ?

Or perhaps could the diversions and fights are organised by them who got nothing to offer to the world no value and useful things others so for them it's useful just to keep chaos and diversion so their non usefulness will be not visible and they can steal and manipulate trough all this when world is in smoke and nobody don't see anything clearly that's when they do their secret moves that's their way to survive in the clear and good world they would't survive because crisis and issues are perfect envoirement for them - is that the issue what we have that world can't get peace and instead of diversion and fight everbody working together in fairness according their merits and skills and talents and contribution ?
