New York Sarah Palin met her first world leaders Tuesday.
It was a tightly controlled crash course on foreign policy for the Republican vice presidential candidate, the mayor-turned-governor who has been outside North America just once.
Palin sat down with Afghan President Hamid Karzai and Colombian President Alvaro Uribe. The conversations were private, the pictures public, meant to build her resume for voters concerned about her lack of experience in world affairs.
"I found her quite a capable woman," Karzai said later. "She asked the right questions on Afghanistan."
The self-described "hockey mom" also asked former Secretary of State Henry Kissinger for insights on Georgia, Russia, China and Iran, and she'll see more leaders today on the sidelines of the United Nations General Assembly meetings.
It was shuttle diplomacy, New York-style. At several points, Palin's motorcade got stuck in traffic and New Yorkers, unimpressed with the flashing lights, sirens and police officers in her group, simply walked between the vehicles to get across the street. Secretary of State Condoleezza Rice, three hours behind Palin in seeing Karzai, found herself overshadowed for a day as she made her own rounds.
John McCain's presidential campaign has shielded the first-term Alaska governor for weeks from spontaneous questions from voters and reporters, and went to striking lengths Tuesday to maintain that distance as Palin made her diplomatic debut.
The GOP campaign, applying more restrictive rules on access than even President Bush uses in the White House, banned reporters from the start of the meetings, so as not to risk a question being asked of Palin.
McCain aides relented after news organizations objected and CNN, which was supplying TV footage to a variety of networks, decided to pull its TV crew from Palin's meeting with Karzai.
Overheard: small talk.
Palin, 44, is studying foreign policy ahead of her one debate with Democratic vice presidential candidate Joe Biden, a senator with deep credentials on that front. More broadly, the Republican ticket is trying to counter questions exploited by Democrats about her qualifications to serve as vice president and step into the presidency at a moment's notice if necessary.
There was no chance of putting such questions to rest with photo opportunities Tuesday. But Palin, who got a passport only last year, no longer has to own up to a blank slate when asked about heads of state she has met.
She also got her first intelligence briefing Tuesday, over two hours.
Today, McCain and Palin are expected to meet jointly with Georgian President Mikhail Saakashvili and Ukrainian President Viktor Yuschenko. Palin is then to meet separately with Iraqi President Jalal Talabani, Pakistani President Asif Ali Zardari and Indian Prime Minister Manmohan Singh.
