No the original goal, as stated by Putin, was to disrupt NATO activities on the Eastern border that were indistinguishable from deploying nuclear capabilities that allowed the USA to continue pursuing its dream of a nuclear first strike.

The initial goal was to end the ethnic cleansing in Donbas(by 22, one million people had fled to Russia), this of course means destroying Ukranian military capabilities involved in that. The stated cassus belli was resposibility to protect, referencing the NATO campaign against Serbia to seperate Kosovo from it. Back then (when the West was bombing Serbia) Russia stated that this would serve as bad precedent case.
