@Sri T and @CJ said some good things.
Peace is an individual thing -- definitely. No group can ever enforce peace, as the New World Order is attempting to do. Their tyranny will blow up in their faces. Just as compassion cannot be legislated, despite what the liberal-progressives think, compassion is still a good thing, but it only comes from the individual.
Spirit is the only way to peace. This mortal species is destined always to be tainted with selfishness and ego. And ego is the barrier to spiritual reawakening.
The physical is the action-reaction realm. Peace cannot exist in such a dichotomous environment. Peace exists through paramita (perfect) generosity, love, compassion, wisdom and responsibility. Peace is possible because of forgiveness. But true forgiveness cannot exist in a logic-based, action-reaction (continuity-based) reality. Logic won't allow a hurt not to be repaid. Letting go of resentment is not reasonable.
But spirit can do all of the required things -- because it is a child of God with the ability to create (discontinuity).
These temporary Homo sapiens bodies that we wear will never know perfect peace, unless we all achieve full spiritual awakening. But once that is achieved, these bodies are no longer needed.
