She did get a Ph.D. but later. It was in the same area, but finished up at NYU.
“In 2011, Clinton transferred back to University College, Oxford, from the Wagner School of Public Service at New York University to complete her DPhil degree in International Relations. She stated this was to be under her preferred doctoral advisor, Ngaire Woods. She finished her dissertation in New York City and was awarded the degree in May 2014. Her 712-page dissertation was titled ‘The Global Fund: An Experiment in Global Governance.’”
So, fresh from her studies, she took a head position at the Clinton Foundation... renamed the Bill, Hillary, and Chelsea Foundation, because Hillary was busy prepping for her 2016 run.
Ok then she did meet the “Cracker Jack 20 Box Tops Requirement for Political Science PhDs for Children of Influential Families “ and got it from a US school!
