Well, let's hope this concession brings some reciprocity. It is usually the case that non-muslim countries accomodate muslim's demands based on their religion, but the opposite is rarely seen (or at least reported).
I may be wrong or simply misinformed, but from what I have read non-muslims who live in muslim countries must be very careful to observe all the laws of the land or face severe consequences.
Even though it may be the case that many people pledge alliance to their host country regardless of their origin, it must be aserious dilema to serve the USA , a country that radical muslim perceive as the quintessential enemy, and its interests as a muslim.
