Not sure how that works, Germany is not going to leave Poland alone. The Whole Polish Corridor/Danzig thing.
IF they leave Poland alone the attack route into the Soviet Union is from Romania.
Germany attacks Poland, but there is nothing that the UK can do to stop it, direct land attacks from France don't happen because they didn't in real life as the French wouldn't allow them. A blockade could and would be enforced but not much else. Night raids can be ignored.
With a path through Poland Russia is very vulnerable and there would be little to stop Germany taking the oil fields then anything can happen
