Nigeria, with a population of 150 million, is the most populous country in Africa, the eighth most populous country in the world, and the most populous country in the world in which the majority of the population is black; Nigeria’s population is almost evenly split between Muslims in the north and the predominantly Christian south; radical Islamic groups have increased their influence in the north by attacking law enforcement units and killing politicians, civil servants, teachers, and others who, according to the Islamists, stand in the way of the imposition of Sharia law in the north; in the past few years these groups have been pushing south, extending their terror campaign to central Nigeria, in the nation’s “middle belt,” where dozens of ethnic groups vie for control of fertile lands.

U.S. attorney general Eric Holder says the danger of homegrown terror “keeps me up at night”: “The threat has changed from simply worrying about foreigners coming here, to worrying about people in the United States, American citizens — raised here, born here, and who for whatever reason, have decided that they are going to become radicalized and take up arms against the nation in which they were born”; the attorney general said that of 126 people who have been charged with allegations related to terrorism in the past 24 months, 50 had been American citizens; Holder dismissed criticism of recent FBI sting operations, which some have argued employed the use of illegal “entrapment,” offering that “options are always given all along the way for them to say, ‘You know what, I have changed my mind. I don’t want to do it’”

Representative Peter King (R-New York), the incoming chairman of the House Homeland Security Committee, was interviewed by Homeland Security NewsWire’s editor-in-chief, Ben Frankel; King’s top three priorities as chairman: examine radicalization in the U.S. Muslim community; air cargo security; and measures to prevent the detonation of dirty bombs in American cities

Long Island congressman Peter King will take over as the new chair of the House Homeland Security Committee — New York state’s lone chairman in the new Congress (and even this only until 2012, when he will be term-limited out of the chairman’s chair, unless he gets a waiver from the Republican leadership); he has been a vocal critic of the Obama administration on a number of issues over the last two years, and says he plans for a much more vigorous — and possibly controversial — committee when he re-takes the gavel; King expressed concern about Obama administration officials’ response to what he calls the “incalculable damage” caused by the massive document leak released by WikiLeaks; “Considering how fast they moved [to file a laswsuit] on Arizona’s immigration law and how determined they were to move against our CIA agents—- there is definitely something missing here,” he asserted

Anwar al Awlaki, the New Mexico-born fire-brand Islamic cleric, from his hideout in Yemen, has been urging Muslims to kill Americans; the Obama administration has placed him on its capture-or-kill hit list, and U.S. special forces and intelligence operatives have been searching for him; the cleric’s father, Nasser al Awlaki of Yemen, sued the U.S. government, arguing that international law and the Constitution prevented the administration from unilaterally targeting his son for death unless he presents a specific imminent threat to life or physical safety and there are no other means to stop him; the suit also tried to force the government to disclose standards for determining whether U.S. citizens like his son can be targeted for death; a federal judge has thrown out the law suit, writing in his opinion: “The serious issues regarding the merits of the alleged authorization of the targeted killing of a U.S. citizen overseas must await another day or another nonjudicial forum”

Five years ago the mayor of Portland, Oregon, decided not to participate in the FBI’s Joint Terrorism Task Force because of concerns about civil liberties; the past weekend’s capture of a 19-year old after he attempted to detonate what he thought was a vehicle bomb near a tree-lighting ceremony in Portland’s Pioneer Courthouse has led the mayor to reconsider his decision

Israel’s covert campaign to derail Iran’s nuclear weapons program continues unabated; the latest chapter: a senior Iranian nuclear weapons scientists, Majid Shahriari, was killed, and a fellow scientists seriously injured, when two groups of operatives on motorcycles approached their cars on busy Teheran streets and opened fire from automatic weapons; the covert campaign has already claimed more than a dozen leading nuclear scientists and engineers (five of whom killed in Teheran, the others while traveling in Europe), as well as several Revolutionary Guard senior officers associated with the nuclear weapons program; in addition, nuclear weapons-related warehouses and depots, located in Revolutionary Guard military bases, were blown up, and disguised nuclear technology shipments to Iran were seized in ports in Europe, America, and Asia; on 16 November, Iran temporarily shut down its uranium enrichment facilities after the Stuxnet virus, designed by the secretive Unit 8200 of Israel’s Military Intelligence, destroyed hundreds of centrifuges

The shipment of radioactive rods sent from Fargo, North Dakota, to Knoxville, Tennessee, posed little threat, but its misplacement underscores the need to track low-hazard materials that could be used in small-scale terrorist attacks, experts say; as al Qaeda has shifted its tactics from 9/11-scale attacks to smaller attacks which aim to create fear and do economic damage, there is growing concern about low-radiation materials which are widely used in research, medical facilities, and industry; such materials may not be suitable for a nuclear bomb, but could be used to create “dirty bombs,” which cause fewer casualties but can release hazardous materials when they explode

Israeli company WeCU says its behavior-based security solution addresses many of the problems now encountered at U.S. airports; the WeCU concept exploits human characteristics and behavior: when a person intends to carry out a particular activity or has a significant acquaintance or involvement with a subject, he carries with him information and feelings that are associated with the activity or the subject; the WeCU system identifies this associative connection by actively exposing the person being screened to stimuli targeted at a specific threat, followed by detection of the person’s physiological reaction, or response, to the stimuli through nonintrusive biometric sensors; the system detects the individual’s reaction without his or her knowledge and without requiring their cooperation, and without interfering with routine activities
