Why did bennett champ clark believe that the neutrality act was necessary?

The correct answer is to prevent from getting d ragged into a conflict that they don't have a true connection too

He was an isolationist and believed that it would be extremely bad to enter the conflict that was not related to them. The neutrality act was thus necessary in order to ensure that the country would remain neutral and would not wage wars that were not related to them and would not meddle in foreign affairs.
