War is cannot be avoided. There will always be war no matter what the date is. It is imbedeed in our genes. War destroy things war also force us to create new things. There are no government that will last forever it will be destroyed by others or it destroys itself. This is just human nature. Humans are predator.
This is simply not true. You say it cannot be avoided, yet I've never killed another human. In fact, nearly all humans have not killed anyone. Peace clearly can be done.
Wars are not what people wish for. Wars are what tyrants wish for, and so they seek a way to deceive the public into killing others for them.
Human nature is not to fear, it is to love. An overwhelming majority of humans tend to bond in unity with others over attack and kill those around them.
The world is turning into a beautiful place. The system would love for you to believe that all is going to hell, for that is exactly what they wish to see in the world - fear, chaos, pain - however this simply is not how the world will unfold. Humans are intelligent, we hold self awareness. The more atrocities that occur, the more we awaken to the state of existence. We are very close to a mass awakening of mankind, the process has been unfolding for years and is rapidly picking up as of recent days.
World peace is around the corner, there is no need to fear life tomorrow, or even life today. See peace and the world will be peace, you attract what you feel.
