Bellum Gerere

bellum gerēre = to make war

"Il est plus facile de faire la guerre que la paix." = It is easier to make war than peace ~ Georges Clemenceau

“Anyone who thinks must think of the next war as they would of suicide.” ― Eleanor Roosevelt

It requires only one side to start a war. So, paraphrasing George Orwell  ― "If appeasers imagine that one can somehow "overcome" an initiator of belligerence by lying on one's back, let them go on imagining it, but let them also wonder occasionally whether this is not an illusion due to simple ignorance of the way in which things actually happen.”
