The peace-loving nations must make a concerted effort in opposition to those violations of treaties and those ignorings of human instincts which today are creating a state of international anarchy and instability from which there is no escape through mere isolation or neutrality.

Context

“No, if those days come, “ there will be no safety by arms, no help from authority, no answer in science. The storm will rage until every flower of culture is trampled and all human beings are leveled in a vast chaos. ”
The peace-loving nations must make a concerted effort in opposition to those violations of treaties and those ignorings of human instincts which today are creating a state of international anarchy and instability from which there is no escape through mere isolation or neutrality. Those who cherish their freedom and recognize and respect the equal right of their neighbors to be free and live in peace, must work together for the triumph of law and moral principles in order that peace, justice, and confidence may prevail throughout the world.” source
