Which side is most likely to exhaust their military resources first? I wonder how much Putin is willing to sacrifice and still keep Russia secure and himself in power?
It also depends on how much troops are willing to fight.
Ukraine already exhausted its military resources, which were meagre in the first place.
But they have enough to launch guerrilla tactics.
Arguably, hes made Russia less secure. He seems to have made NATO stronger, and pushed sone states towards NATO.
