All of these actions are an attempt to destabilize the Martelly government, aimed at a vote-of-non-confidence in January. Aristide plans to collapse the government and replace it with one of his own choice.
Martelly is working hard to satisfy promises made earlier, but these take time, something he did not think of when he made them.
He must act by December 31 or he is in more trouble than he already faces. If he makes a real effort, and the people see this, he can regain some of the popularity he has lost.
