What Will the World Do

Acknowledging that all of the more powerful, larger nations on Earth have waged all sorts of unjust wars, inhumane and murderous invasions of weaker neighbors and nations very far from their own borders as well, I still must ask the question; what will the world do in response to Russia's brutal, terroristic, murderous, and entirely illegal invasion of Ukraine? Is there anything the world can do considering Russian willingness to engage in the use of WMD, such as nukes, chemical, and biological weapons? Is the international community actually unable to halt this due solely to the brutal nature of Vlad The Poisoner?
My heart is aching for the people of Ukraine (as it is for the people of Yemen, Armenia and more around the world suffering from the military abused of more powerful neighbors) and I'm at a loss here for seeing a resolution that doesn't entail Russia completely erasing Ukraine.
