What were Adolf Hitler's goals that were explained in his book mein kampf and what steps did he take to accomplish those goals prior to World War 2?

Hitler wanted to:

• Build a huge empire of pure Aryan people (there is no such thing as an Aryan person either medically or in reality)
• Take the European nations so they could have enough land for this so-called Pure Aryan race.
• Build a Third Reich that would last 1000 years
• He wanted a Final Solution which would eliminate all Jews from the European continent.
• He claimed he never wanted war but how else was he going to seize nations for his goals?
