Conservative columnist Ann Coulter tore into President Obama in an appearance on the Fox News Channel’s “Hannity” show Wednesday night, calling him a “feckless idiot” and charging that the U.S. is “retreating all over the world.”

Coulter was especially outraged by the White House’s “pathetic” use of “hashtag diplomacy” on Twitter to raise awareness of the kidnapping of hundreds of girls by the Nigerian terrorist group Boko Haram.

Michelle Obama recently posted a picture to her official Twitter account that showed her holding a sign reading “#BringBackOurGirls.”

“These idiots think a hashtag is some major policy initiative,” said Coulter. “How about Michelle Obama having a hashtag ‘I’m married to an idiot?'”

Host Sean Hannity asked Coulter if she believed Obama should send in the U.S. military to help Nigeria secure the release of the kidnapped girls.

“It’s kind of a pathetic gesture when we can’t even protect our own ambassador,” she replied in reference to the terror attack in Benghazi. “You can’t take these case by case.”

Coulter also noted Democrats don’t mind “American women weeping for their sons” as long as U.S. military intervention doesn’t boost American interests.

Coulter lamented the decline of American power in the world and placed the blame squarely at Obama’s feet.

“It’s utterly pathetic and embarrassing,” she said. “This guy Obama has done to America in eight years what it took 100 years to happen to the British empire.”
