How does "all war is a symptom of mans failure as a thinking animal" link in with of mice and men?

I am studying literature and I'm going to do an exam soon I would like to link the quote with of mice and men because the author (John Steinbeck) is the one that said the quote, I am hoping that if I could link them together I could maybe get a good mark!

We failed because we were unable to solve anything through war. We behaved as animals because we are unable to work things our in a civilized way, instead we attack each other every chance we get. All this is done through the use of power.

My take is that when civilized men and women resort to violence and aggression to solve problems, we are resorting to our animalistic side. Unlike humans, who can talk problems out and find other solutions, an animals instinct is to attack whatever threatens it. When we forget reasoning and humanity, and instead follow our animal instincts, we fail to use the advantage we have as thinking creatures. At the time, many countries were involved in World WAR II.
