Biden isn't exactly on the good side of this argument. Interesting that the Iranians use Biden to help embolden their policies...

...Bush has been a polarizing figure, but most senators realize that partisanship should never trump national security. In early 2007, evidence mounted that the Iranian Revolutionary Guard Corps was planning terrorist activities in Iraq. An August 2007 National Intelligence Estimate found that "Iran has been intensifying aspects of its lethal support for select groups of Iraqi Shia militants" and that "Explosively formed penetrator (EFP) attacks have risen dramatically." The next month, the Senate considered a bipartisan amendment to designate the Revolutionary Guard Corps as a terrorist organization, an important step to aid nonviolent efforts to deny it funds and financing. Biden was one of only 22 senators to vote against it. "I voted against the amendment to designate Iran's Revolutionary Guard as a terrorist organization because I don't trust this administration," he said. Distrust of the U.S. president is the nature of politics, but skepticism about foreign dictators and their Brown Shirts is the backbone of judgment.
No matter. Biden's political games have made him Tehran's favorite senator. As Gen. David Petraeus struggled to unite Iraqis across the ethnic and sectarian divide, Iran's Press TV seized on Biden's plan for partitioning Iraq and featured his statements with the headline "US plans to disintegrate Iraq." Biden's attack-dog statements about U.S. policy failures emboldened Iranian hard-liners to defy diplomacy. In the Dec. 7, 2007, official sermon, Ayatollah Mohammad Kashani speaking on behalf of Iran's supreme leader, declared, "This Senator [Biden] correctly says Israel could not suppress Hizbullah in Lebanon, so how can the U.S. stand face-to-face with a nation of 70 million? This is the blessing of the Guardianship of the Jurists [the theocracy] . . . which plants such thoughts in the hearts of U.S. senators and forces them to make such confessions." The crowd met his statement with refrains of "Death to America."

Brilliant. And he was chosen to help Obama with foreign policy experience...
Biden, with all his years in the Senate manages to embolden Iran with his policy judgment. So here comes Palin, who no one really believes has FP credentials, and no matter what she says (and arguably her statements aren't that great) she will likely get trounced for it. Even the Kissinger policy has many caveats about setting up conditions to make it so Iran will come to the table, or even start with some back channel negotiations to try and get to some common ground before having open talks with them.
Personally though, I would rather when they ask Palin FP questions she doesn't really have a good grasp on, she just admit it. The people planning to vote for McCain aren't really going to be swayed either way by her not having good FP experience yet - mainly it just gives the media something else to crow about.
It would be good though for Obama to really articulate how he plans to go about having these unconditional talks with Iran.
