The problem with agreeing to the original ask of giving up more land is that it just continues to escalate. in 2014 already Russia took Ukraine and a chunk of Eastern Ukraine. If you give up more this year, what happens in 10 years? Russia will just ask again. Its the same all around the Russian borders. Putin is a thug who just demands more for himself. If you dont fight him now you'll be doing it next year.
