In this episode of UpFront, Mehdi Hasan speaks to the renowned American academic Noam Chomsky about his public spat with the Turkish president, the war against ISIL and Russia's annexation of Crimea. We also look at the ramifications of the Saudi Arabia-Iran feud, and debate the state of Egypt five years after the Arab Spring. Headliner: Noam Chomsky on ISIL, Turkey and Ukraine Noam Chomsky has been described as "arguably the most important intellectual alive". And as one of the world's most celebrated academics, he has published more than 100 books and is a leading critic on United States foreign policy. In the first of a special two-part interview, Chomsky sits down with Mehdi Hasan to discuss the Islamic State of Iraq and the Levant group, Ukraine and Turkey. Chomsky and other "so-called intellectuals" were recently criticised by Turkish President Recep Tayyip Erdogan for supporting Kurdish separatists.

Chomsky also talks about imperialism, and comments on the row between Erdogan and Russian President Vladimir Putin. Part two of the interview to be aired Friday, January 29 at 1930 GMT includes who Chomsky would vote for in the US presidential election, why he doesn't support a full boycott of Israel, and the impact of the rise of Islamophobia.
