Odessa is de facto and de jure part of Ukraine. Nothing for Russia to cede.
It would be like you saying Mexico should cede Boise Idaho....
“ Odessa is de facto and de jure part of Ukraine.”
Odessa is a Russian city and always has been.
Come on. You know Mexico has nothing to do with Boise, Idaho. But, Odessa was founded by Catherine the Great of Russia, and became part of an independent Ukraine only 30 years ago. The culture and language of Odessa remains primarily Russian. And while that doesn’t mean a Russian invasion is justified, it does provide some context as to why Russia desires that land.
