What kind of response did President Roosevelt receive when he suggested, in a 1937 speech in Chicago, that the United States government should be more assertive toward aggressor nations?

The response gotten was mixed. While some supported him, others were against him.

Explanation:

Former United States President Franklin Roosevelt on the 5th of October, 1937 in Chicago gave the Quarantine Speech while dedicating the bridge between the northern and southern Lake Shore Drive where he called for an international quarantine against rampant lawlessness in the world by hostile nations as an option to the political mood of American neutrality that was common at the time.

The speech escalated America's isolationist mood, which caused protest by foes and non-interventionists to interfere. There were mixed reaction to the speech as some agreed while some disagreed.
