Because they have elections aswell and they love their form of goverment. But apparently, when you love national sovereignty, you are a dictator and when you sell your own country to powerful oligarchs, you are a democrat.
Other western countries are also one party states, but with western extravagance so you have two parties. You choice? Hitler's or Mussolini's. How brilliant those "democracies" are.
Even when they have free, independant elections with international observers (cough cough Venezuela cough cough), they are dictatorships because American Elites say so. Interesting how the world works. It's like there is propaganda in the western world targeted at westerners or something.
Why don't you do us a favor a show the public statement from the Carter Center and the UN related to Venezuela. Or you would rather show me statements from great democracies like Russia, China and Iran?
