• "... who the enemy is" or "... who your enemy is."
• "... you figure it out ..."

• Despite his skeptical nature, Franklin did not speak out against propagandistic influences on war (or revolution). Indeed, he was a skilled, if subtle, propagandist himself. Nor did he object to "government" in general (he would have attacked "the Crown" or "Parliament") nor any war that the British government had declared.
• Napoleon, as self-appointed Emperor of France (and war-maker, though most of his conquests were a result of other countries declaring war on him) would not have made the first half of this phrase, as he was the government. Nor, as one whose regime depended on propaganda, would he have suggested people decide for themselves who the true enemy is.
• Neither man, as a rule, wrote their various aphorisms in the second person ("you"). At most they might have used "one"; more often, it would have been "a man" or some third person construction.

O Agamemnon, never ought the tongue
To have a greater influence o'er mankind
Than actions; but whoever hath done well
Ought to speak well; and he whose deeds are base,
To use unseemly language, nor find means
By specious words to colour o'er injustice.
Full wise indeed are they to whom such art
Is most familiar: but to stand the test
Of time not wise enough; for they all perish,
Not one of them e'er scapes.
[tr. Wodhull (1809)]

Agamemnon, it never were fitting among men that the tongue should have greater force than actions. But if a man has acted well, well should he speak; if on the other hand basely, his words likewise should be unsound, and never ought he to be capable of speaking unjust things well. Perhaps indeed they who have brought these things to a pitch of accuracy are accounted wise, but they can not endure wise unto the end, but perish vilely, nor has any one yet escaped this.
[tr. Edwards (1826)]

Agamemnon, never should this thing have been,
That words with men should more avail than deeds,
But good deeds should with reasonings good be paired,
And caitiff deed be ranged by baseless plea,
And none avail to gloze injustice o'er.
There be whose craft such art hath perfected;
Yet cannot they be cunning to the end:
Foully they perish: never one hath 'scaped.
[tr. Way (Loeb) (1894)]

Agamemnon, never ought the tongues of men
To plead more eloquently than the truth.
Good men should prove good speakers, and the bad,
Their very argument grown rank, should find
No specious words to colour evil deeds.
Oh, they are strict professors of the art,
And they are wise; yet in the end of all,
Not wise enough. They perish. None escapes.
[tr. Sheppard (1924)]

Never ought words to have outweighed deeds in this world, Agamemnon. No! if a man's deeds were good, so should his words have been; if, on the other hand, evil, his words should have been unsound, instead of its being possible at times to speak injustice well. There are, it is true, clever persons, who have made a science of this, but their cleverness cannot last for ever; a miserable end awaits them; no one ever yet escaped.
[tr. Coleridge (1938)]

Agamemnon,
A man should talk as he acts.
Good speaks for itself --
The best make bad liars.
The opposite is also true,
Though it ought not to be.
Men with brains can conceal
Whatever they want concealed.
But the brain grows weary.
A bad end's in.
[tr. McGuinness (2004)]

Agamemnon, men shouldn't believe a speech counts for far more than actions ever did. If a man is good in deed, he's good in word. But bad deeds make a man's word rotten, too, and he can't give his injustice a fair gloss. They're clever with their tongues so finely tuned but you couldn't call them clever in the end. Their punishment will come. No one escapes.
[tr. Harrison (2005)]

Never, Agamemnon, should words have greater sway for men than do their deeds. When a man does good, his words ought to be good; when he does evil then his words should be unsound. No one should speak well of injustice. About this last thing, there are those clever fellows who have performed it to perfection but they will all, in the end, be destroyed. None of them have escaped so far.
[tr. Theodoridis (2007)]

Agamemnon, never in the affairs of men
Should the tongue have more power than facts,
Rather, when someone acts well, he should speak well,
And if the opposite, his words should be rotten.
Glib rhetoric may win us over for a while,
but in the end the smooth talkers die foully.
[tr. Karden/Street (2011)]

The things which poets, orators, and even a few philosophers tell us about the love of Glory, are exactly the things we are told at College to encourage us to win prizes. And what they say to children to make them prefer the praise of their nurses to a tartlet, they repeat to grown men to make them prefer the eulogy of their fellows or of posterity to personal advantage.
[tr. Mathers (1926)]

All that the poets, the orators, and even certain philosophers tell us about the love of fame we were told at school to urge us to win prizes. All that is said to encourage children to prefer the praise of their mentors to a piece of pie is repeated to men to make them consider their personal profit less desirable than the plaudits of their contemporaries and of posterity.
[tr. Merwin (1969)]

Things said by poets, orators, even some philosophers, about love of glory, were told to us at the Collège to encourage us to win prizes. What children are told to incline them to prefer a slice of tart to their nurses' approval, is the same as what men are repeatedly told to make them put the commendation of their contemporaries, or that of posterity, before their personal interest.
[tr. Pearson (1973)]

What poets, orators, even several philosophers have said about the love of fame, was told to us at school to encourage us to win prizes.
[tr. Dusinberre (1992)]

What poets, orators, and even philosophers say to us about love of glory is the same as what people said to us in the colleges to encourage us to compete for prizes. What people tell children to make them prefer the praise of their nurses to something silly is the same thing that people repeat to men to make them prefer the praise of their contemporaries or of posterity to their own self-interest.
[tr. Siniscalchi (1994)]

But, we see that Learned men have suche art and cunning to persuade, and such filed wordes to serve their turne: that wrong doth carry the cause away, and Reason cannot prevaile.
[tr. Peterson (1576)]

Men of letters, with their parade of high-flown language, very often make the wrong to prevail and the right to succumb.
[ed. Harbottle (1897)]

We find that learned men, through their grandiose talk, very often manage to have the wrong side win and reason lose.
[tr. Eisenbichler/Bartlett (1986)]
