It is unlikely that the UN will adopt a resolution by which it will have the right to directly topple regimes that have exaggerated its abuses or shown incompetence in governing. The best thing to do is to isolate it economically and diplomatically. Military interventions are an infringement on a country’s sovereignty and it will set a precedent for automatic military interventions in any country surrounded by hostile ones. This is likely to be unpopular by the people themselves as they will see it as an occupation or a continuous domination by foreign powers.

There are also the political calculations of the worth of a massive intervention in a country’s affair, especially when it comes to military action. NATO military intervened in Serbia because the situation there worsened by genocide was a threat to the image of Europe as a free continent and it couldn’t allow those things happen on its soil when the like of them were taking place elsewhere in parts of Africa like Liberia.
What remains as a solution is to starve authoritarian and abusive regimes of all the means to survive and to give a boost to the opposition committed to democracy and to hope for the best to come.
