Because unlike what Oryx and the few guys here who simp his belligcat fed agent rear think, it is not a life or death issue for Russia.I find all this legality talk perplexing, this is a life or death issue for Russia and they're limiting themselves on whether it is legal to send conscript? Is it a joke? I mean Russian has never been a super law abiding people in the first place.
Russia has several layers of escalation left while Ukraine has gone about as far as they can without directly causing WW3.
