What does Arthur say about war?

From the text:

Birling: Glad you mentioned it, Eric. I'm coming to that. Just because the kaiser makes a speech or two, or a few German officers have too much to drink and begin taking nonsense, you'll hear some people say that war's inevitable. And to that I say – fiddlesticks! The Germans don't want war. Nobody wants war, except some half-civilized folks in the Balkans. And why? There's too much at stake these days. Everything to lose and nothing to gain by war.

Birling: Just let me finish, Eric. You've a lot to learn yet. And I’m taking as a hard headed, practical man of business. And I say there isn't a chance of war. The world's developing so fast that it'll make war impossible.
