When I read this, I wondered 'how do wars usually end?' and went to look up recent conflicts [0]. That list makes quite depressing reading; the only thing especially interesting about Ukraine is that the world's top two nuclear powers are locked conflict.

The length of the list defeated me. That being said, I think there are other ways that this war could end. At this point it seems unlikely that the Russians will leave.
