If I remember correctly, it was cluster bombs that were dropped on a major Balkan city (populated by civilians), from U. S. bombers flying safely above the range of SAMs as part of Pres. Clinton's NATO-endorsed military excursion against a country that had not attacked the U. S., a "defensive" reaction against no credible threat to the security interests of the U.S.
When were cluster bomb outlawed anyway? Was it during Carter or Clinton?
