US government policies if put in proper context can be chaged by ordinary citizens here. You only have to know, where to send it. Our representatives are very sensitive to their constituents and hence can hear what we have to say. However, unless the citizens are convinced that we should be doing something that we are not, we usually ignore it. The only exception to that is powerful lobby groups that manage the media and buy favors from the political reps.
Anyway, I am not sure where I am going, but one of these days, I would like to check out OZ land for myself.
