Fake news is spreading easily, it’s because of technology which improves social media and another platforms. Some politicians are sharing their views mostly on twitter and facebook, they are using these platforms to share their views and beliefs which are relating to politics. This can affect the political dialogue because the audience are affected by the politicians and their parties.
If we take Al-Iraq as an example it will be easy to explain how fake news are affecting the political dialogues, America said that Al-Iraq had chemical weapons which was fake news, you can read this in NTI article. Because of this fake news America took a decision to send their solders to Al-Iraq. By taking this step the political dialogue was affected, maybe the Iraqi case will be solved in another way but the fake news took it to that way.
