Today’s edition of quick hits:

* Is Karzai threatening NATO? “In one of his sternest warnings yet concerning civilian casualties, President Hamid Karzai said Tuesday that NATO must stop air attacks on Afghan homes immediately, or face ‘unilateral action’ from the Afghan government.”

* On a related note, Dems want out: “It’s more angst than outright anger, but House Democrats are showing real unity for the first time in pressuring President Barack Obama on Afghanistan — with influential moderates now expressing their impatience alongside the anti-war left that drove the early Iraq war debate.”

* President Obama visits Joplin, Missouri, and promises follow-through: “The cameras may leave. The spotlight may shift. But we will be with you every step of the way until Joplin is restored. We’re not going anywhere. That is not just my promise; that’s America’s promise.”

* While meeting with Joplin’s victims, the president was also seen in one heck of a photograph.

* Yesterday, President Obama marked Memorial Day with a speech at a service at Arlington National Cemetery.

* A shaky Sudanese deal: “Northern and southern Sudanese officials have agreed to a preliminary arrangement on demilitarizing the border between them, the African Union said Tuesday, though some officials from both sides immediately expressed skepticism of the deal, particularly its ability to resolve the dispute over the contested Abyei area.”

* Syed Saleem Shehzad: “A well-known Pakistani journalist has been found dead after being abducted over the weekend in an upscale neighborhood of the capital and receiving repeated threats from Pakistan’s premier intelligence agency.”

* Gen. Martin Dempsey to replace Adm. Mike Mullen as chairman of the Joint Chiefs of Staff.

* As more physicians leave private practice to work at hospitals, they’re moving to the left politically. But that’s not the only reason.

* The World Health Organization had said cellphones pose no public health risk. The WHO position has apparently shifted: “Radiation from cellphones is ‘possibly carcinogenic’ to humans, according to an international expert panel organized by the World Health Organization to evaluate the safety of the increasingly ubiquitous electronic devices.”

* Remember the Fairness Doctrine? A few congressional Republicans are still scared of it.

* Daniel Luzer: “With cuts for America’s state universities getting ever more drastic, is it time for a new design for these schools?”

* Rep. Allen West (R-Fla.) is convinced gay and lesbians can simply choose to be straight. And if they don’t, he says, they shouldn’t serve in the military.

* Oh how I wish CNN were capable of better judgment: “Proving once again that there’s no standard by which many mainstream media outlets are willing to hold sloppy propagandist Andrew Breitbart, CNN this afternoon invited the discredited blogger on the air to discuss the Rep. Anthony Weiner (NY-D) Twitter story. ”
