What reason did Hitler give for taking Austria and the Sudetenland?

Hitler justified the annexation of Austria and the Sudetenland by claiming he was uniting all ethnic Germans under one nation, promoting the idea of self-determination. He argued that the populations in these regions were being oppressed and that incorporating them into Germany was necessary for their liberation. Additionally, he framed these actions as a means to restore Germany's power and prestige following the perceived injustices of the Treaty of Versailles.
