Such an opinion in Europe is of a tiny minority. Much of the West lacks the resolve to survive, especially on the Continent. Here is a link to a message board that is populated by many Europeans -- I get into it with them from time to time:

Our enemies, however, have no such doubts about their survival. Indeed, they hold that their way of life should be the ONLY way of life -- supplanting all others by force.
There is no multiculturalism for them.
They may be at a tactical disadvantage with respect to finanical and military power, but their strategic advantage of resolve is eminently sufficient to overcome that.
The purpose of warfare is to change the enemy's government policy by force. Ho Chi Minh aptly knew that this could be done by demoralizing us at home, by inflicting pin-prick casualties long enough to make us quit. This would not have been successful if he had not seen the mounting self-righteous protests that were occurring here.
If we lose the current World War between civilization and barbarism, it will be lost at home. We have sufficient hardware and technology to defeat them, but that is not enough.
Until and unless we realize that we are in a fight to the death and that we are worthy of survival, by the end of the century the small remainder of humanity will be languishing in a new Dark Age.
