As you can see, the slow implosion of Europe is something of an obsession at this site. I don't think that the average American in particularly aware of the terrible trends outside of sensing that Europe seems unwilling to defend itself or its traditional culture.
The general view here is that Europe is well on the way towards a demographic implosion that has opened up your doors to an Islamic invasion. Your horrifically low birth rates along with your rapidly aging population has forced you to import workers from Islamic countries in order to support you and your economies. However, these "guest workers" intend to rule you harshly and convert your lands into part of greater Islam.
From our perspective, Europeans lack the courage to face this threat much less deal with it. Instead Europeans seem to enjoy directing their anger towards America. This is easy and self-gratifying to do because America will not respond in any meaningful way. On the other hand, we may also be unwilling to bail Europe out of the deep mess they are plunging themselves into.
