The dictionary definition of dictatorship:
noun
1. a country, government, or the form of government in which absolute power is exercised by a
dictator.
2. absolute, imperious, or overbearing power or control.
3. the office or position held by a dictator.
Saudi Arabia is an example of absolute power because their king is also their Prime Minister, and since a king isn't elected neither is their Prime Minister. Compared to this, Qatar is somewhat progressive: they hold elections for the Central Municipal Council every four years in which both men and women can vote (the most recent election being on May 13th, in fact) where women have not only stood for election to the Council but have also been elected.
Obviously this is a relatively recent turn of events, hence I said "somewhat progressive", given their first election was in 1999 and women weren't allowed to vote until 2007, but calling Qatar a dictatorship is flat out wrong - especially given there's plenty of legitimate reasons Qatar shouldn't have been awarded the tournament (mainly the weather, the size of the country, their policy on migrant workers/slave labour, and the feeling they got the World Cup so Blatter could say that the Middle East would be hosting a World Cup rather than saying that they
should be hosting a World Cup...which coincidentally guaranteed Blatter could have a nice little bundle of votes from Middle Eastern countries on the off chance he'd have opposition the next time he wanted to be re-elected)
