Norway: We would like peace and a NAP with you.
Sweden: we would like MPP with you. This would make Prussia, Russia, Britain, and Sweden all mututal allies, forming a "Coalition Of Northern Empires" [CONE].
Austria: your threats against the Confederation of the Rhine are foolish. Not only will we defend their sovereignty, but many of our allies, such as Russia, are poised to divide your nation into occupation areas. Please take back your threats.
Confederation of the Rhine: Brother, we would like to take you under our protection by signing a DPP with you.
Pope: We urge you not to listen to Sardinia's threats. Spanish/British fleets and welltrained Prussian dragoons will be on their way to protect you if the rebel is on his way.
EMERGENCY PLANS FOR TROOPS AND BULLETIN TO TOASTY THE MOD: If Sardinia takes Rome, 1/3 of my troops convoy on British ships to retake the city and turn it over to the Papacy.
This year, settlers convoy on Brit ships to CAM-CON in Africa and settle there.
If any nation attacks me, 1/3 of my troops defend and counterattack. If no attacks on me, but attacks on the Confederation, attack the attackers in their home country [Austria for instance] with all available troops leaving only infantry behind to defend against sneak attacks, especially across sea.
