I hope you don’t believe it won’t be similar the other way around, because it will. Citizens loyal to Ukraine won’t just roll over and accept the annexation no matter what the US and Russian regimes are saying. They’ll most likely keep fighting as they do now.
Honestly, the best that could happen to resolve the issue and not causing it to become a century-long problem with “generational hate” fueling a lasting conflict would be for EU countries as well as other allies (Australia, Japan, South Korea etc) to go all-in and keep supporting Ukraine, in a way it overwhelms Russia. Of course I know how unrealistic that sounds right now…
