Are you actually disputing the factual nature of thepretige's claim? The period in which the US has possessed nuclear weapons and not used them is longer than that for any other nation. Whether or not you find this fact meaningful is a separate question from whether or not its accurate.
Want to test its accuracy? Just ask, how long is that period for the US? It stretches from just after the bombs were dropped in 1945 to today, so ~79 years.
Is there another nation that has both possessed nuclear weapons and not used them for more than 79 years?
Yes, this is also a fact. Both are true. It's up to you to determine the meaning of those facts.
This is just arguing for the sake of arguing. The US is only country that used nukes. The US is also the country that possessed nukes for a remarkably short time before using it. So that to bring up the incidental fact that it is also the country that's gone longest after that without using nukes is ...not utterly urrelevant, but it telegraphs an argument that's fundamentally disingenuous: given that unlike post-WW2 Germany and post-WW2 Japan, the US hasn't reformed, and the only reason no nukes were used thereafter is because there has never been any need to. (It's nevertheless the most stable of the really major nuclear powers, though, like I've said already.)
I was pointing out the obvious flaw in that argument.
To answer the weird question that you keep asking me ---- weird, because the answer's so obvious that I'm surprised you're even asking, and also weird because the factuality is not as cut and dried as you imply: this question: Is it a fact the US owned nukes longest without using them? It's not honest to simply say Yes; and it is dishonest rendering of the actual picture to simply say No.
The fact is the US has possessed nukes for a very remarkably short time before deploying them, and not just once, so the answer is a No. On the other hand, yes, absolutely, after that the US has not used nukes, obviously; and it's had nukes longer than Russia, the UK, or France ---- so the answer is Yes; but even so, even in that limited sense only a technical Yes, because Russia got its nukes very soon after that.
So that, to give you the answer you keep on insisting I furnish: It is disingenuous, even if not technically a lie, to answer that question with a Yes. The honest answer is both Yes and No, with a brief sentence in explanation --- particularly given the fact that the weight of the Yes-it-is-country-that's-longest-without-using-nukes part of the answer is far lighter than the weight of the No-and-on-the-contrary-it's-gone-for-a-crazy-short-time-before-immediately-using-its-nukes part of the answer. (Because Russia got its nukes very soon after, and so have possessed nukes just as long, for all practical purposes; while the US is emphatically the only country, ever, to nuke another.)
Like I said originally, the only way that statement is actually true if there's some difference being implied between "nuclear" and "atomic", or something like that.

TLDR:
The only honest answer to the question is both Yes and No, with a brief sentence in explanation.
To either answer with just a Yes, or to answer with just a No, would definitely be disingenuous, even if technically neither is a lie. As a matter of factuality not of interpretation.
(If you really want to frame your question in such a way that Yes becomes the only answer ---- as you've been trying hard to do, I can't quite fathom why ---- then instead of
focusing on factuality you should focus on
technicality. If you really badly want me to answer you with a Yes, then instead of keeping on asking me, "Is it
factually true that da-duh-dum?", you should, instead, switch your question to "Is it
technically true that da-duh-dum?")

eta again:
Come to think of it, even if you phrase the question like that, with the focus on technicality, even so you are not guaranteed a Yes answer. I can still answer No, and be technically just as correct.
So, the only way you can phrase that question you keep asking me repeatedly, so as to be assured of the Yes answer (that for some reason you seem to be after) would be to put it this way: "Is it technically a lie that the US has owned nukes the longest time without deploying them?" Ask me that, and yes, you'll then be assured of a "No" answer, which you can turn around into a Yes by reversing the construct of the sentence.
So cool: ask me that next time, if you like: and I'll answer with a No, and then you can legit turn it around to a Yes, and go away happy.
