Give in to the bully thats the smart move.
I think this is on a somewhat higher level than bully vs non bully. They don’t have to give in. Sounds like many regular citizens don’t want to hold out because they want to live. Understandable.
Taking advice from people who want you to lose is never a smart move. Putin has made it clear that he believes Ukraine is an illigimate nation and intends to erase it from the map. Given that the only option here is to fight for every inch and send as many invaders home in bags as possible.
Russia humiliatingly had a naval captain KIA in this land battle yesterday for Mariupol. Putinist Russia has proven to be everything it claims Ukraine is: corrupt and hollow.
