Wars are the way of mankind unfortunately and we will never be rid of them until humans don't populate the planet any longer.

Greed and self preservation is built into us by default.

We want bigger ,better and just more dosnt matter what it is , just more.

We envy our neighbours, we think I'll of those doing the same job but better and we push to be the best ourselves.

This is not a species that will achieve peace ever , unfortunately.

Maybe the evolution of humans might be different but I personally don't think this little blue planet will love long enough to see that happen.
