Why did the 1939 cash-and-carry amendment to the neutrality acts favor Britain over Germany?

The 1939 cash-and-carry amendment to the neutrality acts favored Britain over Germany because it allowed belligerent nations to purchase war materials from the U.S. only if they paid cash and transported the goods themselves. This effectively benefited Britain, which had a stronger navy and was better positioned to transport goods across the Atlantic, while Germany, with its limited access to the sea due to British naval blockades, faced significant logistical challenges. Additionally, the amendment reflected U.S. sympathies towards the Allies and a desire to support Britain in its fight against Nazi aggression without direct military involvement.
