Context: I thought of your hand-grenades, of your bayonet, of your rifle; now I see your wife and your face and our fellowship. Forgive me, comrade. We always see it too late. Why do they never tell us that you are poor devils like us, that your mothers are just as anxious as ours, and that we have the same fear of death, and the same dying and the same agony — Forgive me, comrade; how could you be my enemy?

There are those who would stop at nothing to injure our economy and our defence. The price of liberty is still eternal vigilance. I know what a fine part the trade unionists of this country have played in our recovery effort. When they are asked to take unofficial action, which may hurt this country, let them just consider carefully whether the motives of those who ask them to strike are really concerned with the interests of the workers.
