First, The Neutrality Acts helped lead the U.S.
into WWII by setting a set of laws that were created to stipulate when the president proclaimed the existence of a foreign war. The United States could legally sail on a belligerent ship, sell or transport munitions to a belligerent or make loans. The acts from 1935-1937 were specifically tailored to keep the nation out of conflict. America did not help its democratic friends but he helped provoke the aggressors. The neutrality act of 1939 was passed when Britain and France need more materials from America, due to the previous acts that prohibited to trade with them. This act of 1939 allowed European democracies to buy more material from America as long as they transported the goods in their own ships and paid in cash. This would avoided loans or debts and the sinking of American
ships.
Secondly, the cash and carry policy was embraced by the US in 1939 to preserve neutrality while aiding the allies. Which meant that Britain and France could buy goods if they paid full price and transported themselves. The neutrality Acts had imposed an embargo on the military items to nations at war, and these goods were also included in the cash and carry policy. As in the neutrality act of 1939 it avoided any type of loans. If the was at country war or belligerents were coming to get their stuff then the Americans are not sailing and can not be sunk and warfare. We could only sell weapons to European democracies. The lend-lease bill is an act of further to promote the defense of the United States. By this bill we are helping out people who we think are going to defended the US. We are lending weapons to Britain and others, France is no longer in the war because has taken them over. Now we are lending to non democratic nations such as the soviets and now we are starting to ship the weapons. In 5 years we move from not helping anyone to helping specific ones
