- Every spring they send about a million soldiers to farms to help farmers plant crops so they have enough food to get through the winter. It is quickly warming in Korea and it is time to get those crops in the ground, not start a war.
- Every time there is a change in South Korean government or countries reduce foreign aid going to the North they beat their chest and talk of wiping out their enemies.
