Are Muslims less susceptible to naturalization?

The rioting in France brought up an issue that I've often thought about, that of the lack of integration of Muslims into the western communities they migrate into. Looking at America as an example since the country was basically formed by immigrants, although there were some clashes between the different ethnicities, the country became a true melting pot. The ethnic groups maintained aspects of their home countries' identities, but all adopted an American identity and more importantly all had the country's best interest as their common goal, they truly embraced their new home as their new home.

Many Muslims do not fully understand the ramifications of accepting a foreign nationality, either that or they choose to ignore them completely. It's a given that situations in their home countries are less than favorable, but they need to look beyond the immediate improvements to their circumstances, they need to look at the responsibilities that are expected from them with their new affiliations. Taking America as an example once more, look at World War II and how the US military included young men from different ethnicities, many were 1st and 2nd generation immigrants, they fought and sacrificed together for their country. Now Muslim American parents have trouble registering their sons in the required Military Selective Service System, which will be used if there is to be a draft, the military is currently a volunteer force. That's very hypocritical, because when they became citizens they've pledged their allegiance to the US. The issue of Muslims in the military came to surface soon after the September 11th 2001 events.

So what is it that the rioters in France are after? Is it truly an issue of raging against inequality and isolation? Or is it the fact that the rioters simply don't belong to a country that is so different from their belief system? These issues were always there, but with the current rise of extremist Islam and renewed confrontation with the west, the issues surfaced in the violent matter that has been seen on the streets of France for the past couple of weeks. Hopefully that's not a hint of what's to come.
