Some Russians call Barack Obama the American Gorbachev because of his promises to bring change to his country. And the real Mikhail Gorbachev said Thursday that change is what the US wants and needs. "America needs its own perestroika," the former Soviet leader said Thursday in an interview with The Associated Press. With the overwhelming election of Obama, "the entire world felt that America wanted change and was expecting change," said Gorbachev, 77. Obama's detractors in Russia express hope that his policies will lead to the demise of the United States, pointing to the collapse of the Soviet Union in 1991 following Gorbachev's liberal reforms. But Gorbachev said the world needs a strong America, as shown by the current global financial crisis, and he urged Washington to use its power for the good of all.
