I'm ignorant. I'd seriously like to know what he accomplished.
Right off the top of my head, I think Bush, Sr.'s foreign policy and relations with foreign governments was immensely successful. He probably could have gone further in Iraq, but would have faced the same problems that we are seeing now. He was very well-respected among world leaders. I credit him with the success of NAFTA, though Clinton was in office when it was signed. He also presided over what could have been a very rocky time in international relations with the fall of the USSR and transitions of eastern European governments. I think Bush Sr. was a fairly good president, but he did have a hard time connecting with people.
