Answer:
It ensures the United State keeps trade with the aggressor state.
Step-by-step explanation:
To begin with, Neutrality Acts state that a President can announce the existence of a foreign war. In this wise, US citizens are disenfranchised from sailing to the bellicose state, sailing or transporting munitions to the bellicose, or making credit to the bellicose. Suffix to say, this actually angered the bellicose, until when later reviewed.
The scenario that the neutrality acts worked to the advantage of the aggressors can be found in the Japanese aggression to China, when the former touched an explosion in the region. The then President of the United State, refused to call the incident a 'declared war', thus no invocation of the neutrality acts.
With this, the USA continues to sell it's war supplies and materials to the Japanese- an aggressor state. This would otherwise be impossible if the neutrality acts has been invoked.
