Air power alone does not win any conflict. This is well known and proven over and over. Iran is not giving up its nuclear material for the asking, and there is no way for the US to secure without committing ground forces. Iran would love th US to commit ground forces, because it has a massive defensive advantage due to its terrain and decades of preparation for asymmetric conflict.

Air power alone can absolutely win a conflict, provided a compatible theory of victory. What it can't do is effect regime change.
