Hillary was the Commander in Chief...she INSISTED that SERBIA was BOMBED!!!
That is my understanding, as well.
There was a news story shortly after the beginning of the Kosovo Adventure which gave her "credit" for initiating hostilities.
She and Chelsea were then on their "worldwide tour". She purportedly called Bill from Egypt, as I recall, and instructed him to start dropping bombs on Serbia.
Oddly, no rationale was given for the First Lady's advice to a President on a matter of war and peace. But one can speculate that it was fundamentally political advice -- a war would effectively draw attention away from the damaging triune of a.) impeachment, b.) the Cox Report and c.) Juanita Broaddrick.
Urging military action for political purposes does not constitute a credential for the Presidency.
