Samuel P. Huntington said this quote

Arabs and other Muslims generally agreed that Saddam Hussein might be a bloody tyrant, but, paralleling FDR's thinking, he is our bloody tyrant. In their view, the invasion was a family affair to be settled within the family and those who intervened in the name of some grand theory of international justice were doing so to protect their own selfish interests and to maintain Arab subordination to the west.

~ Samuel P. Huntington

It is my hypothesis that the fundamental source of conflict in this new world will not be primarily ideological or primarily economic. The great divisions among humankind and the dominating source of conflict will be cultural. Nation-states will remain the most powerful actors in world affairs, but the principal conflicts of global politics will occur between nations and groups of different civilizations. The clash of civilizations will dominate global politics. The fault lines between civilizations will be the battle lines of the future.

~ Samuel P. Huntington

Some Westerners […] have argued that the West does not have problems with Islam but only with violent Islamist extremists. Fourteen hundred years of history demonstrate otherwise.

~ Samuel P. Huntington

Islam's borders are bloody and so are its innards. The fundamental problem for the West is not Islamic fundamentalism. It is Islam, a different civilisation whose people are convinced of the superiority of their culture and are obsessed with the inferiority of their power.
