World War Z
How we cite our quotes:
In totalitarian regimes—communism, fascism, religious fundamentalism—popular support is a given. You can start wars, you can prolong them, you can put anyone in uniform for any length of time without ever having to worry about the slightest political backlash. In a democracy, the polar opposite is true. Public support must be husbanded as a finite national resource. (3.2.22)
One could make the mistake of assuming war resources equal soldiers and the ammunition they need to shot. At least, we do when playing Call of Duty. But World War Z doesn't forget that public opinion can be just as finite a resource as bullets.
From that moment on we lived in true freedom, the freedom to point to someone else and say "They told me to do it! It's their fault, not mine." The freedom, God help us, to say "I was only following orders." (4.4.31)
Many a solider must decide whether or not to follow orders in World War Z. It's a problem we must all face in our lives, although thankfully—in most cases—without the deadly and horrific consequences present in wartime.
That sound like the enemy we were about to go up against? Was Zack now calling in air strikes and fire missions? And why the hell were we worried about concealment when the whole point of the battle was to get Zack to come directly at us! So backasswards! All of it! (4.7.8)
In World War I, tactics lagged way behind the technology. In other words, people were fighting with machines and mustard gas like they were still using flintlock pistols. In World War Z, the tactics didn't devolve to properly meet the enemy. Got to love those ironic twists.
