Could modernization have protected Korea from colonization?

Could nineteenth-century modernization on Japan's model have prevented Korea's colonization?

Only conditionally: the explanation requires better government organization alongside modernization and gives no assured outcome.

Modernization is treated as only one requirement in this counterfactual about nineteenth-century Korea. The proposed condition is a government able to organize the country and avoid disabling internal disputes. Yi Sun-sin's wars supply an earlier comparison: the interpretation here credits victories achieved despite obstruction from the central government. That example supports an argument about institutions and military effectiveness, without demonstrating that a modernized Korea would necessarily have prevented Japanese colonization.
