I am not so sure. In many places people are too used to the way things are.Very true, but I would beg that if conditions get bad enough overall, such as they did in places like Egypt...well you know there will be trouble then.
I may be a pessimist, but I doubt that we live in an age of reason - or even that there is such an animal..One would hope it being the modern age of reason that our government would know better then to allow things to progress to the breaking point.
Of course I am sure that none of the governments that have been rebelled against in history felt they were near a breaking point...or they figured they could just crush the resistance.
If anything though recent revolutions have shown that no matter how powerful the occupying force...if people want to keep fighting for their cause, they can and do keep fighting.
If they know they have one! But if they think what they have is natural, god's will, their own fault, god's punishment...then they do not have a cause.
