That isn't fair assessment. Europeans have plenty of experience how they failed to manage fixing problems by wars. Also at that time, NATO expansion was the only option on the table, Washington was uneasy about the prospects of some independent european alliance influenced much by the newly unified Germany. So it was only natural they decided to come and showcase fixing problems in ex-yugoslavia.

By the way Europe is in fact fixing American problems, by dealing with of refugees from american (and russian) wars, at the price of political and cultural turmoil.
