Well, it poured tens of billions of military aid on Ukraine over 2 years, supplied tons of intelligence, training, conceded to US made arms being transferred. I'd say that is a lot. More would be better, but I don't think we are in the realms of "reneging on promises". The original agreement was very vague. Was it to mean that the US would defend Ukraine will all it's military might, up to conscripting Americans and sending out nukes? Surely not.
