I don’t think it’s so tricky to analyze: they’ve deliberately sent weapons that are effective for liberation of Ukrainian territory and not sent weapons appropriate for conquesting Russia with.
Germany has its own inner soul struggle regarding moving from a pacifist stance to being able to support Ukraine, but the UK and US support hasn’t been ambiguous in any way I see it.
All of this could change in a second if Pooty either messes with Moldavia/Poland/Baltics or uses um unconventional weapons. I would not consider measured responses to be an open invitation for silliness
