Encouraging emigration and organizing deportations were early, temporary measures.
Think it to the end. Suppose a Jewish state is allowed to exist. And suppose it is successful, thriving, and able to defend itself from its unfriendly neighbors. Something even a Nazi planner can't rule out for certain.
Wouldn't this prove that all the Nazi blather about the inferiority, depravity and social-Darwinian destiny to succumb of the Jews was nothing but a lie? If the Jews succeed, thrive and defeat numerically larger enemies half a dozen times in a row, how will Hitler, Goebbels & Co. look?
So no, it's a danger that realistic, pragmatic Nazis won't risk; while frothing-at-the-mouth, true-to-form Nazis won't contemplate it on principle, they want them exterminated.
So no.
