There is a bit of a coin flip in these type of situations, you see the alternative, and you see the possibility of what could this be, bads and goods of each side, and you never really know whats going to happen. Just to take Syria for example, we know there is a huge war there right? Been over a decade now. Who was the leader there? A guy who was a secular person who wanted to rule the nation without islamist rule, and for this, do bad things and killed people and deported many, and never gave free rights at all. Wel lwe have seen what the other side wanted and won, that is Afghanistan, a nation ruled by islamists right now. I don't see how any side wins, both side looks to be doing terrible stuff.
I have very little information about Sri Lanka, and I am sure they must be doing badly, otherwise why would this happen, and we always like to see people takeover power, but if those people are the ones that really believe in giving it back to democracy. I don't know if that will be the case in Sri lanka. Al lI know is, give it a few years to see if this is a good thing or not, you can't for sure know if this is good or not, it could turn out to be the best thing that ever happend to Sri Lanka, or it could turn out to be horrible.
