It is certainly not true that South Korea's measures have succeeded in eliminating community spread, which has been significant (if not at the same level as the U.S.) since the start of winter. East Asians seem to be more resistant to SARS-CoV-2: their new case rate of about 1/20th the U.S. (1/4 on a per-capita basis) is translating into a death rate around 1/300th of ours. Lockdowns have been largely orthogonal to school closures -- much of Europe kept its schools open while pursuing even more draconian lockdown measures than blue states in the U.S. "Just lockdown, test, and trace harder" is not the lesson from South Korea.
