> Let's not go there.

I genuinely don't know where's "there".

It is a fact, that NATO Article 5 doesn't guarantee anything regardless of other countries' response to USA triggering it, just as it is a fact, that the Budapest Memorandum was mischaracterized in this thread and that both the Europe and USA did help Ukraine. Should we not go where the facts are?

If you're about that the USA should continue helping Ukraine, then I did not question this point of view at all. Pointing out factual errors is not equal to taking a stance.
