The Obama administration has delivered a formal request to Iran for the return of a U.S. surveillance drone captured by Iranian armed forces, but said it is not hopeful that Iran will comply.

President Barack Obama said Monday that the U.S. wants the top-secret aircraft back.“We have asked for it back. We'll see how the Iranians respond,” Obama said during a White House news conference with Iraqi Prime Minister Nouri al-Maliki on Monday.

In an interview broadcast live Monday night on Venezuelan state television, Iranian President Mahmoud Ahmadinejad said nothing to suggest his country would grant the U.S. request.

“The Americans have perhaps decided to give us this spy plane,” Ahmadinejad said. “We now have control of this plane.”

Speaking through an interpreter, Ahmadinejad said: “There are people here who have been able to control this spy plane, who can surely analyze this plane’s system also ... In any case, now we have this spy plane.”

He added, “Very soon, they're going to learn more about the abilities and possibilities of our country.”

On Tuesday, a semiofficial Iranian news agency said authorities have shrugged off the U.S. request. Defense Minister Gen. Ahmad Vahidi said the United States should apologize for invading Iranian air space instead of asking for the return of the unmanned aircraft.

Obama wouldn't comment on what the Iranians might learn from studying the downed aircraft. Defense Secretary Leon Panetta said it's difficult to know “just frankly how much they're going to be able to get from having obtained those parts.
