In recent game as Germany I stretched my empire from the Iberian penisula all the way to China. I had to declare war on Japan in order to do this, they finally offered me a peace which I accepted. Yet all of my puppets and allies stayed at war with them, now I'm stuck being at peace with Japan and with the way doomsday is I have all of their forces sent to me as expeditionary forces. I was hoping that they would take back their forces so I could concentrate more on building up my navy and air force to go back to fighting the allies full time.
