A quote from Islam and the West, the 2008 annual report of the Davos World Economic Forum [pdf]:

Clear majorities in all European countries surveyed see greater interaction between the West and Muslim worlds as a threat. This is true of 79% of the population in Denmark, 67% in Italy, 67% in the Netherlands, 68% in Spain, 65% in Sweden and 59% in Belgium. This corresponds to a growing fear among Europeans of a perceived “Islamic threat” to their cultural identities, driven in part by rising immigration from predominantly Muslim regions. [...]

Although some might expect the United States, Israel and the Middle East to be more likely than Europe to feel threatened by the “other,” the opposite is the case. In the United States (70%), Canada (72%) and Israel (56%) majorities say that greater interaction is a benefit.
