Note: You never mention Milosevic...I wonder why?
I mention the whole existing situation when America went to war, that this was a matter for joint diplomatic action with Russia. Clinton passed on Rwanda when the slaughter of innocents was far worse and the solution much simpler, just send in a battalion and show the flag and they could have done that through the UN. Serbia was a rush to war with no clear goals as in Iraq and an improvised ending, the independence of Kosovo, which could haunt the world for generations.
