The breakdown could embolden the Obama administration's foreign-policy critics

Osama bin Laden was frustrated with the regional groups associated with al Qaeda and was growing concerned with attacks that took Muslim civilian casualties, according to newly released letters taken from bin Laden’s Abbottabad, Pakistan, home.

The letters come from 17 declassified documents released Thursday by the Combating Terrorism Center at West Point, the latest information to come out as part of the one-year anniversary of bin Laden’s death.

The documents are just a small fraction of the thousands collected by Navy SEALs during the 2011 raid of bin Laden’s compound, but they shine some new light on the terrorist who plotted the Sept. 11 attacks.

A year after the killing of Osama bin Laden, Bill Clinton revealed that despite being a former president and the husband of the secretary of State, he had no prior knowledge of the Pakistan raid.

President Carter's failed attempt to rescue the Iran hostages killed eight American soldiers and helped cost him reelection.

Pakistan's fight against the Taliban and other terror groups goes no further than the country's border with Afghanistan, even though many of those groups are carrying out deadly attacks on U.S. and coalition forces from bases inside Pakistan. 

Joint Chiefs Chairman Martin Dempsey said military leaders want to analyze the fallout before deciding to remove Assad by force.

U.S. Ambassador to Afghanistan Ryan Crocker said the Taliban’s attacks that were carried out shortly after President Obama left Afghanistan on Wednesday “had nothing to do with” the president’s visit.

“It took place in an area nowhere near where the president was,” Crocker said in a CNN interview Wednesday. “I think it was a pre-planned attack that simply went off at the time it did but had nothing to do with his visit.”

Senate Judiciary Committee ranking member Chuck Grassley (R-Iowa) said Wednesday that President Obama should not imply that the war on terrorism is over, just one day after Obama addressed the nation Tuesday from Afghanistan to mark the one-year anniversary of Osama bin Laden's death.

In an interview with Radio Iowa, Grassley said that if the president is giving the impression that the U.S. effort against terrorism is over, "he's misleading the American people."

Lockheed Martin’s next CEO says the uncertainty from the potential automatic cuts to the Pentagon could spark a new round of mergers from defense contractors.

Christopher Kubasik, who will take over as CEO of the defense giant at the end of the year, said in an interview with The Wall Street Journal on Tuesday that an uptick in mergers is one potential consequence of the $500 billion cut that the Pentagon faces if sequestration is not undone.
