Hmm...
Iran is probably begging Russia to assist them as per their US/Israel situation, but the Ruzzkies can't spare anyone or give weapons, lest they lose their positions in Ukraine. Putin says "Would like to bro, but can't, by the way, we still good for the next rocket delivery?"
Iran tells Putin to fuck himself, and Putin is left 'holding the baby' in Ukraine. All it would need then is continuous influx of weapons, supplies and support from the UK, EU and US to Ukraine and this conflict is doneski.
