Based on "What if Nazi Germany did not invade Poland?" thread from Shaka Khan

Then I have a question for you ?

What would have happened if Britain and agreed not to enter the war, hence the empire would not have got involved and Hitler would have had a free hand in europe.

Would Western Europe be a German super state and would Britain still have her empire ?
Would we have all the problems in Africa and the middle east ?
would Japan rule the East ?
