Bill Clinton should be at least number four if not higher.
He shaped the post Cold War era and most of the major problems we face world wide are due Bill Clinton's Administration 1960s radical hate America, Maoist CCP friendly world view
The world would have been an immeasurably better place if George HW Bush would have been re elected and Bush had had his chance to solidify his post Cold War vision for the future
Maybe not. GHWB was a globalist/elitist toadie and Bill Clinton was his protege. I suspect that we would be in the same place today if GHWB had been re elected.
