Oh for fucks sake.
I know that Ukraine's civilian population is coming under direct fire from Russia's drones and missiles and it seems unfair that Ukraine can't respond in kind.
But Ukraine intentionally attacking civilian targets is the quickest way for them to lose support from NATO countries and them putting restrictions on use of weapons inside Russia's borders.
It's frustrating fighting from the moral high ground, but it denies Russian allies in the western political sphere an attack angle to pressure for a reduction in Ukraine support.
