Since Russia has already come to the table, that would indicate that Ukraine is winning, according to your logic. Also, the information provided, which shows Russian losses and defeats on multiple fronts, is not in dispute. Dismissing it based on a bland cliche doesn’t validate your take on things.

And Putin can’t possibly launch a nuclear strike. The second he considered it, he would be faced with a full scale coup. No one is stupid enough to risk Russias total annihilation. Not when all they have to do is take him out.
