After a week of dealing with world leaders at the United Nations and G-20, President Obama is getting back to where he left off on domestic issues. "We must bring about a better health-care system in this country not in 10 years, not in five years, not in one year, this year," he said on Saturday at a dinner hosted by the Congressional Black Caucus Foundation. Weaving his diplomatic week into the speech, Obama said that one world leader told him that people in his country were confused by the more outrageous anti-health overhaul protesters. "He says, 'Barack, explain to me this health-care debate. We don't understand it. You're trying to make sure everybody has health care and they're putting a Hitler mustache on you. That doesn't make sense to me, explain that to me,'" Obama said.
