Korean War started in June of 1950, when North Korea invaded South Korea... The U.S. willingly sent troops to protect the liberty of South Korea. After the 3-year war, the Korean peninsula was split in half - North and South. With help from many nations, South Korea has developed enormously. However, North Korea recently unleashed an indiscriminate attack on South Korea. 2 civilians and 2 marines were killed on the battlefield. Yeon-Pyeong island that used to be so peaceful, has now turned into rubbles. South Korea is currently full of anxiety that North Korea might attack again. Many South Koreans are worried that a new war might break out soon. Of course we cannot have another war, but what are we supposed to do if North Korea attacks again...? Obviously our economy is in trouble, too. Korea? Many people do not even know where Korea is. However, the United States of America and Republic of Korea are allies. Like our grandfathers and fathers fought for the liberty of Republic of Korea, we believe that it is a duty to send troops for the peace and liberty of Republic of Korea. North Korea is an organization that destroys global peace. They are even developing missiles that can target the mainland United States. Their nuclear development is threatening the entire world. Something must be done to North Korea.
