Different times need different types of leadership.

My father's biggest achievement was to motivate the South Korean people, to show them we could become prosperous if we worked hard. He taught me to love my country, and serve my country.

I couldn't stand back and watch the strong economy that my father envisioned go to ruins.

This year marks 20 years since the Rwandan genocide -- the world's greatest humanitarian tragedy of the late 20th century. The international community had pledged 'never again' in the aftermath of the genocide in the former Yugoslavia and Rwanda in the 1990s. Yet, we are witnessing today a different type of humanitarian disaster unfolding in Syria and Iraq.

I believe that it is an unchanging value of democracy that ends cannot justify the means in politics.

I have no family to take care of.
