I'm not sure what the western forces game plan is and i'm not sure they actually want to help Ukraine too much, I think they are walking the fine line of wanting to hurt Russia enough and see what happens, but they don't want to truly arm Ukraine because if Russia really loses, they might just nuke.
They could have done much more and given way more, why those are large numbers, it's still not on the scale truly needed to defeat Russia. They still hold back plenty.
They are obviously not going to say that directly in public, so public statements mean little.
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
