I agree that “In God we trust” shouldn’t be our national motto. But I also agree with Zagadka’s points about democracy and diversity. I’m not sure what would be a good replacement for “In God we trust” but I found this list of mottos for other countries, which could perhaps provide inspiration if someone wanted to make one up. Looking through it though, they all sound a bit empty (for lack of a better word) IMO, so I wonder if we really need a motto at all. Anyone here lived in or visited a mottoless country? Do they get along well without one?
New USA Motto: “Motto? We don’t need no stinkin’ motto!”
“What’s a motto?”
“I don’t know. What’s a motto with you?”
Please. Don’t bother. I’ll take care of it.

I’d be against “United We Stand” because idiots would be constantly using it as a rallying cry to make other idiots support the president no matter what damn fool thing he wants to do. “You’re against invading Blargifargistan? Don’t ya know our motto is ‘United We Stand’? We’re supposed to be UNITED behind our president!” We have plenty enough of that bullshit.
Because our country name doesn’t suggest that at all?
Anyway, on topic, I suggest “FOOTBALL IS OURS, YOU CHANGE”

It doesn’t to me. I always thought ‘United’ in USA as meaning simply all under the same legal jurisdiction of the federal gov’t. It never once occurred to me that might mean “united” as in “United We Stand”.
How about Puellae formae sunt bonos?
I think we can all agree on that. 
‘Give me a woman who loves beer and I will conquer the world.’
pretty much says it all right there.
Fabricatum diem, punc.
with profound apologies to Pterry…
‘SPQR’ has already been used, and doesn’t really fit. ‘SPQA’ would look snazzy on the front glacis of a M1 Abrams…
At this stage in our history, the most fitting national motto would be:
“You got a better idea?”
If you want something to inspire our conquering heroes. “When Come Back, Bring Pie” sets the right tone. How’s that written in latin?
According to my handy-dandy pocket dictionary:
Cum Redeo, Addo Laganum
Laganum is listed as ‘cake’, but the Romans appear to have had no pie. Certainly explains the bloody gladiator stuff.
Unfortunately, if we were to inscribe ‘CRAL’ on our tanks, it may get mistaken for Krull, which probably has just been released in the theaters in Afghanistan and Iraq. They may then think that Americans live in a huge fortress that teleports around, and all sorts of problems may ensue.
Rather, I recommend:
*Cum Redeo, Addo Pumilio * (When come back, bring dwarves.)
Certainly nothing can go wrong with that plan, and we get to see ‘CRAP’ written all over the place.
“Where Oil Goes To Die”, possibly?
“E pluribus, Seinfeld”
Yes, most of my life I’ve lived in Australia, which thankfully has no motto. Within Australia, I lived in New South Wales, which has a motto that hardly anyone knows and no one understands (“Orta recens quam pura nites”), so it might as well not have a motto.
United we stand, financially divided we all fall…

“You talking to us?!”
“Feeling lucky, punks?”
“What the hell are YOU staring at?!” </Duckman>
Or, if you want to go sunshine and lollipops, “Can’t we all just get along”
“Mostly harmless”
“We try harder”
or my choice, from Phil Foglio’s BUCK GODOT comics; it took place in a future where humans had colonized a bunch of planets and lived in a sort of Federation with other species. There was a gigantic space station that had embassies from all the home planets, and Humanity’s motto, emblazoned on the front of the building, was just “Let’s Be Pals!”
I dunno. “All Your Base Are Belong To Us” seems to be closer to the current Administration’s philosophy.
So I first thought of a smartass response here and looked up the slogan for Hogwarts in the Harry Potter books:
Draco Dormiens Nunquam Titillandos.
And then I sort of parsed it out and it’s not so bad.
Roughly: Never tickle a sleeping dragon.
Sort of a motto and a warning to those who would irritate us.
Not so different from the “Don’t Tread On Me” motto of the old revolutionary flags.
