Cleansing Serbs out of Krajina was the right thing to do? How so?
Without US intervention in Bosnia, the Bosnian Muslims and their Croatian allies would have overrun the country in a few months, and then Serbia would have gotten involved and you would have had a much, much wider war.
Meanwhile, the Serbs were committing genocide in the areas they controlled. US intervention did much to stop the slaughter of hundreds of thousands of Croatians and Bosnians.
