You gain world domination. Nothing goes wrong. Portugal spontaneously fails to explode and becomes the seat of your government. But you ruined this thread.
The guilt at having ruined this thread eats away at you, year on year, ruining your enjoyment of the achievement.
Finally, you die, an unhappy monarch of a tense and nervous world. Your funeral pyre is incredibly grand, and indeed swells up until Portugal finally explodes in a magnificent blaze saluting your ultimately futile achievement.
I wish for a flameproof Portugal.
