The United Nations have approved punishment against the Al-Qaeda affiliated group Boko Haram, United States officials say. That’s the group reportedly responsible for kidnapping nearly 300 Nigerian schoolgirls.

This news comes as a team of U.S. Air Force troops has begun its mission to help search for the girls. Officials say the 80 troops arrived in Chad to fly a predator surveillance drone over northern Nigeria where the girls were kidnapped last month.

The girls may have been split up into smaller groups, and the leader of Boko Haram has threatened to sell them as sex slaves.

After attending a classified hearing with FBI and U.S. intelligence officials, Rep. Sheila Jackson (D-TX) told Fox News, “That $70 million dollars is being transferred through a number of Al Qaeda groups. And frankly, that means that this group is here to stay. And for us, it means that we must put them in the eye of the storm. They’re reckless, they’re thugs but they are strategic.”

Jackson said the concern right now is to keep the girls alive and warned sending troops on foot could inadvertently lead to the girls being harmed.

The American forces in Chad are not combat troops, but because they’re armed, President Obama was required to notify congressional leaders.

Senior judicial analyst Judge Andrew Napolitano weighed in on whether U.S. intervention is legal.

The judge told Shepard Smith, “There’s no international legal basis for them to be there. They weren’t asked there by the government of Nigeria. They’re not there because it’s a United States national security interest.”

He concluded that the U.S. government’s move is illegal. “Feeling sorry for somebody is not a sufficient basis for sending American men and women into harm’s way, especially against the madmen and crazies who kidnapped them in a jungle with which we’re unfamiliar.”

Judge Napolitano said that American drone strikes have killed more children than this terror group.

“The president’s drones have killed more young women than these crazies from Boko Haram have kidnapped,” he said.
