Malaysian Prime Minister Najib Razak told reporters over the weekend that "deliberate" action by somebody on board accounted for Malaysia Airlines Flight 370 veering off course.
There is still much that is mysterious about the fate of Malaysia Air Flight 370, but there is emerging consensus that the passenger jet bound for Beijing changed course, flying west over the Indian Ocean and flew for at least four hours. This tends to suggest that there was a human intervention, rather than a mechanical failure.
Sen. Dianne Feinstein is not a bomb thrower.
Nothing gets conspiracy theorists going more than a passenger plane crashing under mysterious circumstances.
Ukrainian security officials are complaining that unknown attackers are interfering with the mobile phone services of members of Ukraine's parliament, making difficult political decisions about what to do about Russia's incursion last week into Crimea that much harder.

From around Aleppo in western Syria to small areas of Falluja in central Iraq, al Qaeda now controls territory that stretches more than 400 miles across the heart of the Middle East, according to English and Arab language news accounts as well as accounts on jihadist websites.
The Obama administration has framed its defense of the controversial bulk collection of all American phone records as necessary to prevent a future 9/11.

After the attack on the Westgate mall in Nairobi, Kenya, substantial attention was given to the some 40 Americans who have traveled to fight for Al-Shabaab in Somalia during the past several years.
It was the first major terrorist attack in history in which the group that mounted the operation used Twitter to announce to the world it was responsible.
Of all al Qaeda's affiliated groups, the Somali terrorist organization Al-Shabaab has over the past several years had the deepest links to the United States. Some 15 Americans have died fighting for Al-Shabaab, as many as four of them as suicide bombers in Somalia, and an American citizen even took up a leadership role in the group.
Al-Shabaab, al-Qaeda's brutal Somali affiliate, has claimed credit for the attack by multiple gunmen at an upscale shopping mall in Nairobi, Kenya that has already killed at least 59 people.
Aaron Alexis, the troubled civilian contractor and Navy veteran who killed a dozen fellow workers this week at the Washington Navy Yard, is far from the only veteran or active-duty serviceman to plan or carry out mayhem directed at U.S. military targets during the past decade.
We are about to mark the 12th anniversary of 9/11. Since then, al Qaeda and its affiliated groups haven't launched a successful attack in the United States.
As they contemplate military action against Syria, one of many considerations members of Congress and Obama administration officials have to weigh is how a U.S. strike against the regime of Bashar al-Assad might effect the already complicated, even poisonous, state of Sunni-Shia relations in the region.
Barack Obama came to Washington to end wars. Not to start them.
Why has the Obama administration been so reluctant to intervene in Syria? There are a host of reasons -- American fatigue with war, President Barack Obama's disinclination to start another conflict in the Middle East, and the splintered, fractured opposition to Bashar al-Assad.
What is widely recognized as the most authoritative study of the United States' responses to mass killings around the world -- from the massacres of Armenians by the Turks a century ago, to the Holocaust, to the more recent Serbian atrocities against Bosnian Muslims and the ethnic cleansing of the Tutsis in Rwanda -- concluded that they all shared unfortunate commonalities:
Ayman al-Zawahiri, the Egyptian-born leader of al Qaeda, has seen this movie before: An Islamist party does well at the polling booth only to be overthrown by a military coup that then plunges the country into chaos.
On Friday the U.S. State Department issued a worldwide travel alert because of an unspecified al Qaeda threat.

Killing the man proved easier than killing his ideology.
In her classic 1962 study, "Pearl Harbor: Warning and Decision," Roberta Wohlstetter shows how the Japanese surprise attack on the U.S. naval base on December 7, 1941, should have been less surprising than it appeared at the time because there were warning signs known to the U.S. government that such an attack was possible.
The news that Canadian law enforcement on Monday arrested two men accused of planning to derail a passenger train in the Toronto area has attracted much attention, in part, because the plotters are also charged with "receiving support from al Qaeda elements in Iran."
We don't yet know how or why the Tsarnaev brothers, the alleged Boston Marathon bombers, decided to carry out their attacks, but a look at how their stories correlate with those of some other terrorists living in the West could provide some answers to the questions that many are now asking about them.

The appearance Friday in a lower Manhattan courtroom of Sulaiman Abu Ghaith, Osama bin Laden's son-in-law and one-time al Qaeda spokesman, to face charges of conspiracy to kill Americans underlines the perhaps surprising fact that members of bin Laden's inner circle have been living in Iran for the past decade or so.
George Venizelos, the FBI's assistant director in charge, asserted Thursday in a written statement that the recently arrested "Sulaiman Abu Ghaith held a key position in al Qaeda, comparable to a consigliere in a mob family."

On Wednesday, three senior U.S. senators sent Michael Lynton, the CEO of Sony Pictures, a letter about "Zero Dark Thirty," the much-discussed new movie about the hunt for Osama bin Laden, which described the film as "grossly inaccurate and misleading."
The proliferation of semiautomatic weapons in the hands of Americans of the types that were used in the Newtown massacre is sometimes framed as a public health issue in the United States.
The star of the new film "Zero Dark Thirty" is a flame-haired female CIA analyst Maya (played by Jessica Chastain) who is obsessed with finding Osama bin Laden.
"Zero Dark Thirty" is a likely shoo-in, deservedly, for Oscar nominations for best director (Kathryn Bigelow) and best screenplay (Mark Boal) and perhaps a slew of other categories.
Ambassador to the United Nations Susan Rice, a possible nominee to be the next secretary of state, came to Capitol Hill Tuesday to perform a private mea culpa to key Republican senators for her erroneous initial public statements about the perpetrators of the attack on the U.S. consulate in Benghazi in September in which four Americans were killed.
In choosing a new CIA director to replace David Petraeus, President Barack Obama has a range of well-qualified candidates to choose from, although some of the most qualified were in management roles at the CIA when controversial interrogation techniques were used by agency interrogators questioning al Qaeda prisoners and the CIA was maintaining secret prisons overseas to detain members of al Qaeda.
Historians will likely judge David Petraeus to be the most effective American military commander since Eisenhower.
The man charged Wednesday with attempting to blow up the Federal Reserve Bank of New York, the latest alleged jihadist to be charged in a law enforcement sting, may or may not have had the capability to create a major terrorist incident.

A decade ago, the United States had a virtual monopoly on drones.
On November 2, 2004, Dutch filmmaker Theo van Gogh was bicycling to work in Amsterdam when he was shot eight times at close range. He died instantly, but in a fit of rage, his assailant, Dutch-Moroccan Mohammed Bouyeri, also attempted to cut off his head with a machete.

On Monday, Republican presidential candidate Mitt Romney called for the appointment of a special prosecutor to investigate a series of recent leaks that critics charge are designed to bolster the national security credentials of the Obama administration.
President Obama is celebrated and criticized for greatly accelerating the number of CIA drone attacks in Pakistan, but the similar covert war that he has launched in Yemen has received considerably less attention.
The news that Abu Yahya al-Libi, the No.2 leader of al Qaeda, is now confirmed to have been killed in a CIA drone strike in Pakistan's tribal region along the border with Afghanistan further underlines that the terrorist group that launched the 9/11 attacks is now more or less out of business.
It's the diplomatic equivalent of hosting both the World Cup and the World Series in the same country on the same weekend.
At a campaign event Monday in New Hampshire, Republican presidential candidate Mitt Romney asserted that he too would have made the decision to send a U.S. Navy SEAL team to kill Osama bin Laden in Abbottabad, Pakistan, telling reporters, "Of course, even Jimmy Carter would have given that order."
We climbed the stairs to the third floor, where Osama bin Laden died early in the morning of May 2, 2011. I stepped into the bedroom where he was killed and looked up at the ceiling, where you could still see the patterns of blood that had spurted from bin Laden's head when the bullet fired by a U.S. Navy SEAL tore through the terrorist leader's face.
There is no better way for historians to assess Osama bin Laden's thinking and the real state of al Qaeda as it was understood by its leaders in the years after 9/11 than the "treasure trove" of more than 6,000 documents that were recovered by the U.S. Navy SEALs who raided bin Laden's compound in Abbottabad, Pakistan, a year ago.
Nearly one out of every five NATO soldiers killed in Afghanistan this year were killed by Afghan police or army forces. Nine of the 16 victims were U.S. soldiers.

David Petraeus.
