There was no genocide and ethnic cleansing was done and is still being done against the Serbs.
I probably wasn't clear enough in speech on that, as it was not an accusation. When two sides in one country are willing to fight as long as it takes for one side to prevail, genocide may be the result. Not many civil wars are as restricted to only men fighting, as happened in the USA. And civil wars involving much about religion/ethnicity are often worse.
Partitioning is one attempt to separate two ethnic sides in such conflicts. India and Pakistan are one example. Arrangements like that don't stop the violence completely, but there is hope for eventual peace and less chance of one culture completely extinguishing the other.
