Are Ukrainians and Russians different? They are almost the same people...fighting against each other.
Evil are those who want this war to continue, using Ukrainian soldiers as human shields.
So Russian soldiers aren't used as human shields by those who want the war to continue? People like Putin, that is.
The weaker side has always to surrender...so peace is made and no more life is wasted.
Imagine if the Allies had adopted this logic during their most difficult periods of loss in World War II, or if Indians had just accepted British colonization instead of resisting it.
The logic you're using might work in a jungle, but it should never be accepted by anyone who values human life and rights.
