“Pray for our troops.”

May He continue to help them to peace with honour, & the victory over Juda & Antichrist in British garb.
Letter to Margarethe Landgraffin von Hessen (20 April 1941), quoted in John C. G. Röhl, Wilhelm II: Into the Abyss of War and Exile 1900-1941 (Cambridge: Cambridge University Press, 2014), p. 1262

Quotes 1990s, 1990-1994
Context: The point of public relations slogans like "Support Our Troops" is that they don't mean anything... that's the whole point of good propaganda. You want to create a slogan that nobody is going to be against and I suppose everybody will be for, because nobody knows what it means, because it doesn't mean anything. But its crucial value is that it diverts your attention from a question that does mean something, do you support our policy? And that's the one you're not allowed to talk about.

A Prologue (1939) to Oliver Goldsmith's The Good Natur'd Man (1768).
Context: Our fate lies in your hands, to you we pray
For an indulgent hearing of our play;
Laugh if you can, or failing that, give vent
In hissing fury to your discontent;
Applause we crave, from scorn we take defence
But have no armour 'gainst indifference.
