Events such as the Nanking Massacre and Japanese-American internment  solidified a country's right to act to protect its own security

Explanation:

On December 13, 1937, the Chinese army surrendered to the Japanese imperial army, which had invaded the country eight days earlier. The surrender took place in Nanjing, then China's capital and triggered a horrendous massacre, many Chinese were killed in cold blood and many women were taken as sex slaves. The Japanese-American massacre acted similarly, leaving great suffering for the people and leaving deep marks on the nation. The massacres happened because the defense of the attacked country was flawed or nonexistent. For this reason, we can conclude that events such as the Nanjing Massacre and the Japanese American solidified a country's right to act to protect its own security.
