So long as there are men, there will be wars.

As long as there are sovereign nations possessing great power, war is inevitable.

As long as there are slaughter houses there will always be battlefields.

Yes, a war is inevitable. Firstly, there's you fellows who can't be trusted. And then there's the multitude who mean to have bathrooms and white enamel. Millions of them; all over the world. Not merely here. And there aren't enough bathrooms and white enamel in the world to go round.

War always brings death and destruction and that can never be a good thing

Sooner or later every war of trade becomes a war of blood.

War is always a struggle in which each contender tries to annihilate the other. Besides using force, they will have recourse to all possible tricks and stratagems in order to achieve the goal.

War was always here. Before man was, war waited for him. The ultimate trade awaiting its ultimate practitioner.

The growth of the power of Athens, and the alarm which this inspired in Sparta, made war inevitable.

The man with the greatest soul will always face the greatest war with the low minded person.

The ancestral voices were prophesying war because ancestral voices never shut up, and they hate to be wrong, and war is a sure thing, sooner or later.

[Standing armies] constantly threaten other nations with war by giving the appearance that they are prepared for it, which goads nations into competing with one another in the number of men under arms, and this practice knows no bounds. And since the costs related to maintaining peace will in this way finally become greater than those of a short war, standing armies are the cause of wars of aggression that are intended to end burdensome expenditures. Moreover, paying men to kill or be killed appears to use them as mere machines and tools in the hands of another (the nation), which is inconsistent with the rights of humanity.

The greatest evil that can oppress civilized peoples derives from wars, not, indeed, so much from actual present or past wars, as from the never-ending and constantly increasing arming for future war.

Europe is overpopulated, the world will soon be in the same condition, and if the self-reproduction of man is not rationalized... we shall have war.
