The Russians need to develop some bigger balls. They willing jumped into the deep end of a nasty civil war in a region known for byzantine politics, longheld grudges and incompetent militaries (Israel aside). Losses were inevitable. Instead they follow their usual playbook; fire off any number of wild theories (the French did it! It’s the Israeli’s fault!) to muddy the waters before whining that everyone’s anti-Russian.
Russia didn't jump into anything.
