UN, our best hope for freedom

The Korean War was the first war waged to restore peace under the single flag of the UN. Considering that there were 93 independent countries in the world at the time and that only 61 were UN member states, it could be said that 65% of the countries in the world took part in united efforts to fight for the freedom, peace, aid and restoration of the Republic of Korea.
