If I may answer your question base on the Holy Book, I should say "no". The world is already been corrupted and I believe, that's how the world runs now! logically speaking, if the world will have a peace forever, then the world will not be ended. When the new Heaven and Earth are made, then that's the time we may experience the eternal Peace. :)

maybe it depends on how you define peaceful.

My answer is "NO".

We can not make the world peaceful,but we can make us peaceful,friendly!

Hello Icy, It was never absolutely "peaceful" .
