Col. Caare made bad choices. Rather than deal his grievances within the boundaries of the Republic, he thought, of all people, the failing Garowe Administration will provide him a safe heaven and a launching base.
Probably it made a perfect sense for Dr. Gaas when he is not on his prozac medication i.e. when hulicinating. But for President Deni, hosting anti-peace elements and providing a launching base, was a big mistake. Which is why he is limiting Col. Caare's movements, most likely under house arrest.
