In spiritual maturity, the opposite of injustice is not justice, but compassion. Not me against you, not me straightening out the present ill, fighting to gain a just result for myself and others, but compassion, a life that goes against nothing and fulfills everything.
The highest form of intervention that an individual may offer within a given situation, is not to ask for something to be, rather to become that which is desired. If peace is THE DESIRED REALITY within the global matrix, peace must BECOME THE REALITY within the local matrix of your experience. You must BECOME THAT PEACE.
