Lust – Turkey: for their desire to join the EU, which is being dangled like a carrot in front of them.
Anger – Iran: Fairly self-explanatory.
Pride – United States of America: 'God Bless America' and all that jazz.
Sloth – Italy: If you've ever tried getting anything done in Italy, you'll understand.
Envy – France: They should just face the fact that English is the global language.
Gluttony – China: For their rabid consumption of energy (I limited myself to one entry per country, several could have had this spot).
Greed – Russia: Largely due to their control of oil to other nations, and for using it as political leverage on nations like Ukraine.

Anger: Israel. Drawing inspiration from the God of the Hebrew Bible who seethed with wrath and still furious at the world for allowing the Holocaust the country smashes any who oppose it.
Pride: US. Bellicose and arrogant. Revels in its status as the world’s only superpower. Starts wars just for the sake of them, Iran is next.
Envy: Britain. Still obsessed with class. Move on, UK, move on!
Sloth: France. Notoriously work shy labour force, 35 hour week. Best selling book extolling “indolence”.
Lust: Botswana. Despite massive gov’t effort and free condoms AIDS now infects over 25% of population and continues to rise. Botswanans just like to do it. Sorry, Precious.
Gluttony: US (hey, it’s a big country with a lot of sins!) “Supersized me!”
Greed: frequent flyers allied with China. Spewing out carbon and endangering the planet.
