CameraMan, the rebels and allies only form a small percentage of the population and are unlikely to cause much trouble if some of their main demands (namely a return to democracy and a referendum on the constitution regarding the role of the monarchy).
Many foreign powers, and especially the US, have been supporting the monarchy in its take over of all powers and are now pressuring the parties to accept the king's offer. There are many reasons for their concerns is to preserve a certain peace and stability but their position is hardly one that resonates with an ideal of democracy. This, I am afraid, could translate in a certain anger towards Americans and Westerners in genral... I haven't read anything about this apart from the few kidnapings which happened a few years ago by maoist rebels but who knows how this volatile situation can turn.
