I'm sorry but this is such utter nonsense. If Israel was a remotely serious pretender to the title of being a democracy it would stop banning people who don't like its policies. Chomsky is a US citizen and attacks US policy relentlessly. He has criticized British foreign policy and is not banned from entering the UK. Why? Because the UK today is a real democracy; not a state that wears a misspelled name tag that states "demockracy."
