South Korea wasn't a democracy for most of its history and it shows as soon as drastic measures need to be taken. The first reaction among the populous in the West is resistance against any form of government mandated measures due to a deep mistrust. Add to that federal structures versus centralised government and you get to the results we see today.
Calls for strong leadership end in dictatorships because measures taken in times of crisis tend not tobe taken back once the crisis is over. This is nothing new - this is how the Roman Empire got its emperors after all.
