International Security and weapon making (YEN-CHIEH CHEN)

After World War II, our world is getting peaceful. However, we still have some conflict between countries. Therefore, we make weapons to protect our countries. A lot of groups and countries want to take America down so America has right to make weapon for self-defense. However, America attacks other countries for helping their citizen. No one knows that America attacks them for benefits, revenge, or helping. We need weapon for defense but weapon bring war.
