There really is no other way...
From Create Your Own Story
You wait for a year, becoming a beloved figure in the local community, then shoot yourself at the back of a Nazi while yelling "No! Don't attack me, thug!" In German, which you've learned to speak.
Hitler is revealed as the power-hungry maniac he is, and is lynched. Then, disatisfaction with the Wiemar Republic propels the Communists into power. The world is a Communist state inside the century.
Bet you weren't expecting that, huh?
You could stop it, but...
U DED, BRO.
THE END.
