What US policy, enacted before Pearl Harbor, permitted belligerents to purchase non-military goods under the “Cash and Carry” provision?

💡 Explanation:

The Neutrality Act of 1939 revised previous acts to include a "cash-and-carry" provision. This allowed warring nations to buy non-military materials from the US, provided they paid immediately in cash and transported the goods on their own ships, marking a shift away from strict isolationism while maintaining US neutrality. This preceded the US entry into WWII following the attack on Pearl Harbor in December 1941. The Lend-Lease Act, a more substantial aid program, was passed later in March 1941.
