Each state pursues its own interest's, however defined, in ways it judges best. Force is a means of achieving the external ends of states because there exists no consistent, reliable process of reconciling the conflicts of interest that inevitably arise among similar units in a condition of anarchy.
— Kenneth Waltz
Almighty Conflict Is Inevitable quotations
Conflict is inevitable but combat is optional.

Conflict is not inevitable, but disarmament is.
.. everyone now accepts that if there is a default by Saddam the international community must act to enforce its will.

The problems raised by a conscious direction of economic affairs on a national scale inevitably assume even greater dimensions when the same is attempted internationally. The conflict between planning and freedom cannot but become more serious as the similarity of standards and values among those submitted to a unitary plan diminishes.
This inevitability of conflict motivates us today and echoes the reminder that freedom is not given away and our national security is not achieved without sacrifice.
An artist's early work is inevitably made up of a mixture of tendencies and interests, some of which are compatible and some of which are in conflict.

I think that the first responsibility of an artist is to follow truth, and the innate original forces and energies that are within them. At the same time, I also think, collectively, that there has to be a place for artists to reflect and deal with the society they're living in. I think that great art inevitably reflects some of the drama and trauma and conflicts that exist in the outer world.
Is war an inevitable outcome of competing interests in a complex society? In other words, would war be the same even if human nature were very different? There are mathematical models of large groups working together that lead to conflict on a reliable basis. So there's a whole other view of war that is not psychological at all.
Law and justice are from time to time inevitably in conflict .
.. . The jury ... adjusts the general rule of law to the justice to the particular case. Thus the odium of inflexible rules of law is avoided, and popular satisfaction is preserved ... That is what jury trial does. It supplies that flexibility of legal rules which is essential to justice and popular contentment.

Conflict in close relationships is not only inevitable, it's essential.
Intimacy connects people who are inevitably different.
We're always projecting our moral categories on things.
I think that's inevitable. But capitalism places no particular value on morality. Morality in the market is enforced by contract and regulation and law, because morality is understood to be in conflict with the motive force of greed and accumulation.
Conflict is inevitable, the source of all growth, and an absolute necessity if one is to be alive.

A host of positive psychological changes inevitably will result from widespread economic security. The dignity of the individual will flourish when the decisions concerning his life are in his own hands, when he has the means to seek self-improvement. Personal conflicts among husbands, wives and children will diminish when the unjust measurement of human worth on the scale of dollars is eliminated.
When human beings live together, conflict is inevitable. War is not.
We are not one people. We are two peoples. We are a people for Freedom and a people for Slavery. Between the two, conflict is inevitable.

All conflicts can be resolved. Wars and conflicts are not inevitable. They are caused by human beings. There are always interests that are furthered by war. Therefore those who have power and influence can also stop them. Peace is a question of will.
"The true Islamic concept of peace goes something like this: "Peace comes through submission to Muhammad and his concept of Allah" (i.e. Islam). As such the Islamic concept of peace, meaning making the whole world Muslim, is actually a mandate for war. It was inevitable and unavoidable that the conflict would eventually reach our borders, and so it has."
...Choice in every form is conflict. Contradiction is inevitable in choice; this contradiction, inner and outer breeds confusion and misery.

Why, sir," said he, looking about him, "what splendour I see: gold lace, breeches, cocked hats. Allow me to recommend a sandwich. And would you be contemplating an attack, at all?" "It had crossed my mind, I must admit," said Jack. "Indeed, I may go so far as to say, that I am afraid a conflict is now virtually inevitable. Did you notice we have cleared for action?
Since [narcissists] deep down, feel themselves to be faultless, it is inevitable that when they are in conflict with the world they will invariably perceive the conflict as the world's fault. Since they must deny their own badness, they must perceive others as bad. They project their own evil onto the world. They never think of themselves as evil, on the other hand, they consequently see much evil in others.
