When peace is disturbed at any place, then peace of all countries is at risk.
No peaceful victory is as magnificent as a supreme martial victory.
(Theodore Roosevelt said)
It is greater not only to simply win but to make good use of the victory.
Peace nourishes the farmer even when his land is rocky, while the war brings misery to the farmer even when his land is very fertile.
The quickest way of ending a war is to lose it.
