So you think we should forcibly liberate Ukraine? With what?
It is in our interest we (the west NATO nations) supply Ukraine with the weapons it needs to rid itself of the Russian invaders. We can support Ukraine and show Russia our support is unwavering without military combat against Russia. As it is we are doing exactly what we did/did not do with Germany prior to it’s invasions of European nations. That resulted in WWII. This weakness is far more likely to lead to war we will have to fight.
