Would Nazi Germany have still been able to pull off something like the Manstein Plan had it had to also fight the USSR in 1939-1940? For the record, I am thinking of an anti-Nazi alliance being successfully created by Britain, France, and the USSR in 1939 and, for whatever reason, Hitler deciding to still believe that it's a bluff and thus go to war over Poland and Danzig in 1939. In such a scenario, with Nazi Germany being at war with Britain, France, and the USSR, would something similar to the Manstein Plan actually still be within Nazi Germany's capabilities to successfully pull off?

Any thoughts on this?

Also, for reference:


The Manstein Plan basically advocated for tricking the Western Allies into advancing into the Low Countries (Belgium and perhaps the Netherlands as well) while the main Nazi assault is going to occur further south--specifically in the Ardennes. Afterwards, the Nazis' goal was to race up to the Atlantic Ocean and thus encircle the Western Allied forces in the Low Countries as well as in the northernmost tip of France. Nazi Germany was able to successfully pull this off in 1940 in real life.
