War is dangerous. Ukraine has been attacked and is fighting back. They're warning people that the area they are fighting in is dangerous and they don't want anyone to get hurt.

Do you assume Ukraine should prioritize commercial airline safety over their own sovereignty and their own commercial airlines, which have consistently been in danger for years?

There is not a safe way to conduct war. I'm sure Zelensky would prefer to stop the fighting, but that option currently means the death of Ukraine entirely.
