To clarify- What I mean is did Hitler plan to stop fighting France and the UK if they had also declared war on the Soviet Union when it invaded Poland, whom they had sworn to protect. Everything I have ever read suggested that Hitler did not want War with the west, but a mutually beneficial relationship. He wanted Russian lands and an Alliance with the Allies would have helped secure that. Is there any evidence of this scenario occurring?
I talked about this recently in a post before, (http://www.reddit.com/r/AskHistorians/comments/1xh8ou/why_didnt_france_and_britain_declare_war_on_the/cfbflyr)
To shortform, the allies weren't going to declare war on the Soviet Union, because they realized Germany was the biggest threat.
