I think just about everyone has positive feelings for Madagascar, if only because of the (not very realistic) movies. But, sadly, the political crisis there that began in January of last year has continued, and now there is
open fighting in the streets of Antananarivo between different factions of the security forces.
One question I have, and I cannot find anywhere, is whether the leader of the government forces (Col. Richard Ravalomanana) is related to the ousted President (Marc Ravalomanana). The dissidents seem to be in favor of Marc Ravalomanana, or at least against the man who deposed him (Andy Rajoelina).
In terms of broader implications, there probably are not many. Madagascar is rather isolated, and it is unlikely that the unrest there will spread to any neighbors. However, I hope that the upcoming elections offer a way for all sides to stand down, but the past does not suggest that it will. Marc Ravalomanana won election that way, and was deposed by those who were upset. If Rajoelina's side does not win the election (Rajoelina himself is not running), another coup could happen.
We'll have to wait and see.
