I feel like “darts” is the odd item out in this list of (presumably) Americana.
In any case, a gentle reminder that the USA has hundreds of missiles carrying nuclear warheads ready to launch…
…and that the President of the United States has virtually unrestricted nuclear launch authority.
I don't think Quark is naming American things, he's naming Earth things, and all he knows is stuff Bashir, Sisko, and O'Brien have shown him, which includes darts.
