The phrase “war broke out” seems disingenuous to me, like us humans were the passive victims of naturally-occurring violence. It's not an “oops of war”, it's an “act of war”.

Acne is something that “breaks out”, war on the other hand is started, and no matter whether we believe in the necessity of a given war, we should respect that, at a fundamental level, war is collectively (as a human race) our fault.
