The course of empire does not runs smooth. Lately, it seems your every action is cursed, and here is the latest nail in the coffin: you have heard that the leaders of various powerful empires are to gather in the city of {0} to discuss topics of international cooperation. Arms regulation, environmental protections, and international trade are on the docket. However, they seem to have forgotten to invite your favorite world leader: you. Though disappointed, you ruefully acknowledge the truth: perhaps your personal policy of avoiding treaties with others has its downsides. What will you do now?
Send envoys to request a place at the conference. Your people would not expect any less.
They will pay for their oversight. Send a message by imposing new tariffs on all international goods.
You don't need them. Double down on your empire's protectionist stance by focusing on domestic industries.
