"Amid all the media frenzy around the Nigerian underwear bomber and how America should have stopped him before he tried to blow up a passenger plane on Christmas Day, a critical piece to the counter-terrorism puzzle seems to have been missed: where in the world is the Nigerian President? Normally, after such a horrific incident, President Obama would be on the phone with his counterpart, discussing what went wrong and agreeing on ways to work better in the future to prevent such attacks. But this couldn’t happen because Nigeria’s President Umaru Yar’Adua left his country for medical treatment in Saudi Arabia on November 23rd and hasn’t been seen or heard from since."

He further wrote: "The failed terrorist attack by Umar Farouk Abdulmutallab on Northwest Flight 253 highlights that Nigeria’s power void is dangerous for the U.S. as well. The foundation of a counter-terrorism strategy is to build cooperative partnerships with friendly nations. This means sharing information and helping to build security capacity in places like Yemen, Afghanistan, and Nigeria. But we cannot have a partnership if there is no one on the other end of the line."

“President Barrack Obama could not have been discussing with Nigeria’s security adviser or Mike Aondoakaa (the Attorney-General),” the source added. “He had nobody to discuss with.”
Also, Nigeria lacks a strong lobbying group in the US, which sources say, might have been useful immediately after AbdulMutallab was arrested.

“The lobbying group would have swung into action immediately AbdulMutallab was arrested to sensitise the American authorities,” the source said.
During the President Olusegun Obasanjo administration, Goodworks International, an American lobbying firm, was hired for Nigeria. But the contract was discontinued when Yar’Adua came into power.
