In 1940 the time factor was still against Hitler. The Allies didn't plan to sit at the Maginot Line forever, with their economic superiority they'd build up a military advantage over Germany and attack it at some point in the future. The more the war stalled, the more comfortable their situation became. It was Germany that had to find a solution to the stalemate quickly. So the Allies didn't need to reach a negotiated settlement anytime soon.

> But without signing the Pact he couldn't have occupy Poland and reach a common border with the SU so he can attack it later.
Another big issue is that without the pact Germany's economy would be crippled, Soviet raw materials were the primary factor keeping it alive in 1940-1. The secondary factor was resources seized from occupied countries aswell as their very limited production, and those were only conquered because the eastern border was safe.
> Just because such higher units (I'm referring to the tanks only) exist it doesn't mean they were kept together (I will look it up ofc), their subunits could been dispersed, they could been detached to other units.
Well, divisions were kept as a monolithic units of maneuver by default, detachments were the exception. Hearts of Iron isn't too far from reality in depicting them as the basic unit in the field.
