Let the bastards who start the war be the only ones to fight it.

I will gladly share my plate with civilians from any nation, for I will have more in common with them than any national leader, talking head or oligarch.

"I feel then, as I feel now, that the politicians should be given the guns and told to fight amongst themselves, rather than organizing nothing more than mass murder."
Harry Patch, last surviving veteran of World War One
Why don't Presidents fight the war? Why do they always send the poor?
- NGL, heads of state challenging each other to exhibition boxing matches would be incredible. It would also radically alter who gets on the ballot for general elections, and we'd have to deal with concussed presidents and such. At the same time, the stakes would probably be state-level things (resources, borders, land, tariffs, embargos, sanctions, etc.), so everyone's emotional state around a spectacle like that would be off the charts. People would riot after a loss.
as a great wise man once said; what's so civil about war anyway. it feeds the rich while it buries the poor.
- Did you wear a black armband when they shot the man who said: "Peace could last forever"?
Kat and Kropp get in an argument over the war as they rest from an hour’s worth of drill (occasioned by Tjaden’s not saluting a major properly). Kat believes the war would be over if leaders gave all the participants “the same grub and the same pay,” as he says in a rhyme. Kropp believes the leaders of each country should fight each other in an arena to settle the war; the “wrong” people currently do the fighting.
All Quiet on the Western Front

I know people don't care for Moffat-era Who, and for good reason, but gd Capaldi had some real bangers. The whole speech is incredible.

There are no adults. Never have been

Be the adult you want to see in the world.
- Eww. Hell no
  I want to still have the curiosity and empathy of a child on my deathbed. I want to grow and change until I die.
  What is an adult but someone who does paperwork and is confidently wrong about how the ever changing world works?

I mean, that's an easy one: "It doesn't."

calvin (and bill) was especially based during c+h run. his takes on deforestation and urban sprawl were great.

It doesn't. It just keeps you in the running to survive until the problems are resolved.

But then again, humans have never really needed any excuse to kill each other.

Reminds me of the time someone asked why I joined the military. The answer was because I was young and needed the money. They expressed disgust that I was willing to kill people for money. I think it's a much better reason than because of disagreements about imaginary friends.

if you're being invaded, then killing aggressor side soldiers solves very practical problem of getting invaded by them

unless you're saying that the ethical thing to do is to keel over and die in this situation

Because one faction have soldiers and the other no, if it had it too there would be no kill each other

it doesn't really solve any problems, it's just that a few assholes like to create noises
