Yeah, I don't fully agree with their decision to intervene in the Ukrainian civil war, just as I don't agree with Ukraine's shelling of Donbass in violation of Minsk II, or with the coup and banning of opposition parties that led the disputed territories to declare independence.
The best case scenario, as has been the case since the start, is for a peace agreement to be reached as soon as possible to prevent further loss of life. Which reactionary government controls the disputed territories isn't worth people dying over.
