Looking for love in all the wrong places or Goodbye American exceptionalism

While historic analogies are never perfect, Obama's stark efforts to change the U.S. image abroad are reminiscent of the stunning realignments sought by former Soviet leader Michael Gorbachev. During his short—by Soviet standards—tenure, he scrambled incessantly to shed the ideological entanglements that were leading the communist empire toward ruin.

But Obama is outpacing even Gorbachev. After just three months in power, the new American leader has, among many other things:

—Admitted to Europeans that America deserves at least part of the blame for the world's financial crisis because it did not regulate high-flying and greedy Wall Street gamblers.

—Told the Russians he wants to reset relations that fell to Cold War-style levels under his predecessor, George W. Bush.

—Asked NATO for more help in the fight in Afghanistan, and, not getting much, did not castigate alliance partners.

—Lifted some restrictions on Cuban Americans' travel to their communist homeland and eased rules on sending wages back to families there.

—Shook hands with, more than once, and accepted a book from Hugo Chavez, the virulently anti-American leader of oil-rich Venezuela.

—Said America's appetite for illegal drugs and its lax control of the flow of guns and cash to Mexico were partly to blame for the drug-lord-inspired violence that is rattling the southern U.S. neighbor.

At a news conference ending the three-day Summit of the Americas on Sunday, Obama was asked to explain what a reporter called this emerging "Obama Doctrine."

He said that first, he remains intent on telling the world that the United States is a powerful and wealthy nation that realizes it is just one country among many. Obama said he believes that other countries have "good ideas" and interests that cannot be ignored.

Second, while the United States best represents itself by living up to its universal values and ideas, Obama said it must also respect the variety of cultures and perspectives that guide both American foes and friends.

"I firmly believe that if we're willing to break free from the arguments and ideologies of an earlier era and continue to act, as we have at this summit, with a sense of mutual responsibility and mutual respect and mutual interest, then each of our nations can come out of this challenging period stronger and more prosperous, and we can advance opportunity, equality, and security across the Americas," the president said.
