My private theory includes that this cuts both ways. Everybody wants to continue with business as usual: peace talks with a puppet government installed, lifting of sanctions for some concessions here and there, and then go on as if nothing happened.
This state of indecisiveness wasn't anticipated by anyone. Germany did even want to skip the sanction part since the war would be over in 3 days.
Now we have to actually deal with it; and the plans on both sides are made up as we go.
