What Were Hitlers Plans for WWII?

The main purpose for invading Poland was to start WWII. Despite the treaty Hitler was

 able to successfully attack Poland in about a week because of the falty radio brodcast.

 He also wanted to test his new tactic know as the Blitzkreig where hundreds of planes,

 tanks, and soldiers attacked Poland. Hitler believed that Germans had more of a right to

 Poland then the Polish people did, which was one of his justifications for the invasion. 

Moreover, with Poland occupied Germany would become an even greater superpower. 

Poland also served as a buffer state for Germany as protection from the Soviet Union.
