Any changes that do happen will not be because suddenly the West discovered their true friends in Serbs, but because the exigencies of the world thus created will necessitate new allies (not friends), and thus they will be used as they were abused at the pleasure of the powers to be.
Judging from the goings on in Bosnia, this process of slowly empowering Serbs to clean up the mess left behind did not make it to the agenda of the imperial powers there. The viceroy in Bosnia is still a staunch friend of SDA and their Islamic agenda.
The problem is, even if the Serbs do eventually return and reclaim what is theirs, they will have ruins of what's left of monasteries that cannot be rebuilt, of artwork that cannot be recreated, or culture that has been destroyed in a genocide presided over by the very ssame people who will now they really didn't mean to because they are really our friends.
Oh I hope Serbs never fool themselves again that they have friends in the West. That belief has made them useful fools too many times in the past.
