When the US requested assistance, Europe provided.
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.
Friendship among nations sometimes involves transactions that transcend the pure material considerations, and this shift in alignment is not desirable by anyone.
That's what I meant by "let's not go there".
But I see that basically we are in agreement and I also agree that article 5 interpretation could be dicey.
In the history of the Alliance there is only a single country that invoked article 5, and it was the US with 9/11 that lead to the United Kingdom, Canada, Germany, Australia, Italy, New Zealand to send resources and troops to help with Afghanistan.
And managed to get people involved in Iraq namely United Kingdom, Australia, Poland.
And this situation was way worse and way less called for than the Ukrainians defending themselves...
EDIT/NB: I listed just the major contributors, some other countries participated in different ways and at different levels, but still this is important to mention here...
