The architects of the Treaty believed that language would reduce violence. This was their reasoning in one quote: "Words cut deeper than swords, but they do not kill," a quote whose flaw Eurostate revealed.
Words do not kill. That is true but only to an extent. Words do not kill… immediately. Words do not kill immediately but they accumulate and when meaning accumulates beyond containment, the consequences can become catastrophic.
In conclusion, the transition from sword to word did not end warfare.
What it did was merely change the battlefield.
