I think ExBethelite makes a good point.
From the outside, everyone (well, many Jews, Christians and the non-religious west) thinks that Muslims seem so unified and powerful, but I get the feeling the religion is really a hard, brittle shell around a 'soft centre'. Outwardly, Islam seems impenetrable and undefeatable, and is spreading aggressively into the west, but if you look closely at many majority Muslim nations, the foundation is very weak within. There are many sects of Islam at war with one another, and many of the religion's adherents make an outward show of devotion but in private are keen to drop the rituals and adopt more 'western' and materialistic lifestyles, for example the young people in Iran. Look a little closely, and the outward bombast and aggressive confidence of Islam (mixed as it often is with the political leadership) appears it could collapse inwards at any time. Unfortunately, when it does I fear the results may be very bloody - more even than we've seen already.
The same is true of other religious groups who have previously ruled by strong central control, including the JWs. Such groups are losing grip, and even many members who outwardly seem invested in these groups (PIMIs as we might say) are inwardly just waiting to break free or walk away as soon as they get a chance.
