Basicly, discuss what you'd do if you owned any country in the world. Describe what laws you'd make, what you'd do with the money, which other countries you might end up killing along the way by accident or deliberatly etc.
If I owned the United Kingdom...
I'd change the National Anthem to "I've got a Lovely Bunch of Coconuts".
I'd make Idiot Hunting the national sport.
I'd have every car in the country be something loving awesome like a Dodge Charger or some stuff like that.
I'd have all the hot bitches.
I'd blow all the money on fancy stuff.
I'd inevitably make America start a nuclear war after one obesity joke too far and kill every single person on the planet.
