The early "deprogammers" would persuade someone to leave a cult, then consider their job done and go on to the next person. But in fact, that was only the beginning of the now ex-cult member's road to recovery. Similarly, many rebellions in countries would depose their lousy dictator, and think that's what needed to be done, so now we can rejoice and relax. Again, that was really only the beginning of repairing the country.
Humans seem to have this flaw where they think that once the first step of something is done, they can sit back and relax. In fact, the task has really just begun.
"Revolution, once its makers pluck up the courage, is the easy part. It is what follows that is so hard... Overnight, people who weren't allowed to decide anything their whole lives have to decide everything. It is not a learning curve, it is a sheer cliff." [The New Middle East: The World After the Arab Spring, by Paul Danahar, p. 49]
