South Korea has more than enough military capability to stop any northern aggression. South Korea is also technologically a fairly advanced nation that is almost literally just a screw driver turn away from immediately building a far more advanced nuclear arsenal than the north can dream of.
But although the south will certainly be victorious in a conflict with the north, the conflict will be messy both for Korean pennisula, and for the larger east Asia region. Keep in mind the larger east asia region collective has over one of a half times the economic output of the United States. So American presence their to deter such a conflict is amply worth the cost.
