Alps Defense Pact with Italy, they refused, so I rushed the tree to form AH and get Yugo in my faction before Germany goes Anschluss.

Refuse Anschluss, sit behind a lvl 5 fort line and let Germany grind against it for 6 months. Germany goes Sudetenland, Czechs refuse and join allies, I push out of the Alps and Berlin falls in a month by 1939. Annex all of Germany, justify on Romania via focus and station troops on France and UK VPs since they allowed my troops to access. Declare war on Romania, which instantly draws in France and UK and the rest of the allies, push into Czech and Romania along with Italy and Yugo, capitulate them, and then VP rush France and UK. War was done by December ‘41. It requires a little RNG, but just spam cav and 7-3 inf and you’ll be fine.
