They made teepees because they were nomads. (a nomad is a member of a people having no permanent abode, and who travel from place to place to find fresh pasture for their livestock.) Teepees were easy to set up and put away for traveling purposes. Teepees were made out of stretching buffalo skin over a skeleton of 20-30 wooden poles, all slanted towards a central point and tied together near the top. A flap at the top allowed smoke to escape, and a flap at the bottom served as a doorway.
The "Day of Infamy" speech given by President Franklin D. Roosevelt on December 8th 1941, was given in front of the US Congress. His goal in giving this speech was to explain what happened and Pearl Harbor and ,more importantly, ask for Congress permission to declare war on Japan.
It is clear that this speech is supposed to paint the Japanese military in a negative light, as FDR calls the attack "cowardly" and "dastardly." Along with this, he is trying to invoke a sense of patriotism among the Congress, as this attack killed American soldiers/citizens. His speech rallies Congress behind this cause and results in Congress approving of war with Japan.
