What's the world come to if we've gotta 
send kids out to the battlefield?
Was wird nur aus dieser Welt, wenn wir
Kinder in den Kampf schicken müssen?
Qué mal está el mundo si tenemos que
enviar a unos niños al campo de batalla.
Dans quel état est le monde
si on est contraints
Dove andremo a finire, se dobbiamo mandare
dei ragazzini sul campo di battaglia?
