Answer: A) Roosevelt hinted that the US could not always remain neutral and might have to “quarantine” other states to keep the peace.
Step-by-step explanation:
President Roosevelt was very concerned about the increasingly chaotic world during WWII and feared the US would not be able to keep up with its isolationist politics. In October 1937, during a speech in Chicago, he called for international assistance to “quarantine the aggressors” threatening world peace. This early attempt had very little effect in the Congress and in the national feeling, something bigger was still needed to change everybody's conception about the importance of the nation to step in the war, the infamous Japanese aggression.
