Friction was developed over which country would be able to call the territory of Texas as part of their own nation. Both America and Mexico wanted the territory of Texas and this caused them to fight over it. Thus started the Mexican-American War.
Explanation:
A. Germany was invading other European countries, the Allies declared war on Germany, Roosevelt signed the Lend-Lease Act but still refused to enter the war, Pearl Harbor was attacked, the United States entered the war.
The United States wanted to remain neutral and have no involvement in the war, however, the US did send resources to the Allied Powers. In 1939, Congress passed the "Cash-and-Carry" Provision; later in 1941, the Lend-Lease Act was passed. So far the United States did not have any direct involvement with the war, the US only supplied its allies. This all changed when the Japanese bombed Pearl Harbor; the US had to abandon their policy of neutrality and take action.
