Uh, look it up on wiki? If Japan has nothing to do with the PU, then you cannot request that the allies make peace with japan as part of a condition on your peace. Either you are co-belligerents or seperate.
The fact is, we absolved Japan as to any obligation to enter the war and, now that we think through our position more carefully, it was completely their own decision to do so. We doubt that our alliance with them would have changed Japan's actions at all. As such, we withdraw our requirement of a peace offer to Japan.
Land is not the only thing fool, the seized territories contain Prussian commercial assets and citizenry. And the original intention was on returning it to Prussia, once you stopped being foolish, though now with the entry of France and US that doesn't really seem necessary.
So, you started with good intentions and then turned the war into a land-grab? Although we do not see you as necessarily have started out with these intentions, the ends are more important than justification or means; your demand for Prussian territory in Africa, while very realistic and acceptable in our view, does not make the end result any different from what Romania or Japan were hoping for in the beginning of their entrance into this war.
You attacked Russia without any diplomatic formalities or attention to the just conduct of war, and your actions elsewhere seriously threatened the peace and security of the global status quo. You actions may have had reasonable cause, but they are still in error.
This is a very reasonable position, and we do not see any holes in it. The fact is, however, the entrance of the United Kingdom into the war was no different until we threatened British interests which was not,as to your own admission, not until we annexed Sweden, which was not something that was, realistically, going to happen. Your entrance into this war has done little to help the situation for anyone, least of all the United Kingdom.

You must choose a side, Greece. If you pick ours, you will be at war with France until a separate or complete peace is signed with them; if this is your wish, then continue on your current course of action. Otherwise, we advise you to remain neutral for the time being.
