Final answer:
The second neutrality act included a 'cash and carry' provision that allowed warring nations to purchase non-military supplies from the U.S., provided they paid in cash and used their own ships for transport, as part of the Neutrality Act of 1937.
Step-by-step explanation:
The Neutrality Act of 1937 introduced a second provision to maintain U.S. neutrality amid growing global tensions. This legislation extended the ban on arms sales to warring nations and introduced a "cash and carry" policy for non-military supplies. Enacted during a period of international turmoil preceding World War II, the policy allowed nations at war to purchase non-military goods from the United States, provided they paid in cash and were responsible for transporting the supplies using their own ships.
The "cash and carry" approach aimed to prevent the United States from becoming entangled in foreign conflicts while offering economic support to nations opposing Axis powers. By engaging in trade on a cash basis, the U.S. sought to stimulate its economy, promote self-sufficiency, and avoid direct military involvement in the escalating global hostilities.
