In what ways is there a civilisational conflict between Islam and the West?

Samuel Huntington theorised that in a post cold war world, the main source of global conflict would be culture, and talked of a 'clash of civilisations'. This clash would take place between the Muslim and Western worlds especially.

There can be seen to be an ideological conflict between radical Islam (for example groups which practice Salafism or Wahhabism and want the establishment of shari'a law and an Islamic caliphate) and the West in that such groups view Western intervention in the Middle East as undesirable due to the culture of secularism, materialism and individualism and seek to purge their societies of such values. However it should be understood that groups whose values are at odds with the west are not 'civilisations', nor can the entire Islamic religion be termed its own civilisation as it is diverse and multifaceted, much like Christianity. Similarly, the western world is not one 'civilisation' and should not be treated as such - it is extremely diverse in terms of religion, culture, and ideology and therefore unless there is homogenisation of the entire western 'world' there can never be a civilisational conflict between Islam and the West.

Despite some prominent groups in Muslim countries favouring Shari'a law and scriptural literalism, there are many that seem to want to embrace 'western' values such as democracy and pluralism. This is exemplified in the case of turkey, which while largely Muslim is secular in nature (religion and government are kept separate). Turkey's continued attempts to join the EU despite being a Muslim country is further evidence that there is not a civilisational conflict between Islam and the West. Additionally the 2011 Arab Spring radically reshaped the political complexion of the Muslim world after four dictators in Tunisia, Egypt, Libya and Yemen were removed in favour of western style democratic reforms including free and competitive elections and protected civil liberties. It could be said that the Muslims world is in the process of Westernising, or in the very least is in the process of becoming more democratic and so Huntington's thesis is becoming less relevant. Moreover, the close relationship between Saudi Arabia and the US despite the former's Wahhabi monarchy demonstrates that conflicting ideologies do not equal conflict.
