After the death of Osama Bin Laden in May 2011, the global jihadist movement seemed to have become fragmented and considerably weakened. The impressive victories of ISIS in Iraq and the practical reactivation of the concept of the “caliphate” by ISIS leader Abu Bakr al-Baghdadi are particularly worrying as they creates a new unifying idea for disparate jihadist groups around a common strategic project. Since Bin Laden’s death, these groups were fragmented, but they might now be able to connect and share an ideology — and, probably, funding given the wealth of the “new caliph.” The “Caliphate Utopia” may reveal to be also a much more efficient tool for jihadist recruitment, especially among young Westerners. This change might point to the marginalization of the leader of al-Qaeda, Ayman al-Zawahiri, an Egyptian, who has not been able to impose himself after Bin Laden’s death. But at the same time it indicates the end of the fragmentation and the beginning of the reunification of jihadi groups around the world within an even more dangerous organization. The global war against terror may finally start.

An 81-page report, released last Thursday by the Stimson Center and authored by a bipartisan panel of former intelligence and defense officials, warned that the present targeted drone strike policy could represent a “slippery slope” toward never-ending war. The report stresses that drone operations should always be “having a positive effect on U.S. national security and not trading short-term gains for more negative longer-term strategic consequences.”

Dozens killed after Boko Haram car bomb attack in north-eastern city of Maiduguri, the birthplace of Islamist militant group. In May 2013 the Nigerian president announced a state of emergency in three north-eastern states, and the Nigerian military deployed tens of thousands of troops to the area in an effort to fight Boko Haram. That campaign has been a complete failure. The extremists have been attacking with more frequency and deadliness in recent months, defying assurances by Nigerian security forces and government that they were getting the situation under control.

Azamat Tazhayakov and Dias Kadyrbayev, two friends of Boston bomber Dzhokhar Tsarnaev, are set to go on trial on charges of impeding the investigation into the deadly attack. Opening statements are scheduled for 7 July. Law enforcement says Tazhayakov and Kadyrbayev admitted they took Tsarnaev’s backpack from his dormitory room three nights after the bombing after they saw photographs of Tsarnaev on the news identifying him as one of the suspects. The backpack contained fireworks that had the black powder scooped out.

Cost is largely absent in the key debates around the use of unmanned drones in war, even though drones are a cost-effective way of achieving national security objectives. Drones will never completely replace soldiers, but the drone-vs.-human being debate is becoming less important in the current strategic climate. The operating environments where drones are deployed — countries such as Pakistan, Somalia and Yemen — do not emphasize “hearts and minds” strategies where the human element has traditionally been valued as a force multiplier. Instead, objectives in these countries involve attacks on specific individuals, with operational data obtained by signal intelligence beforehand. Human contact becomes even less desirable given that a key tactic of combatants in these weak states is attrition with the aim of creating low-level civil conflicts. The end goal of these actions is to inflict high economic costs to the adversary. As a result, this remote and analytical method of engaging militarily leads to substantial cost efficiencies.

Lawyers for Mohamed Mohamud, a U.S. citizen who lived in Oregon, have been denied a motion to dismiss his terrorism conviction, with the court affirming the legality of the U.S. government’s bulk phone and e-mail data collection of foreign nationals living overseas. Mohamud’s defense team claimed the surveillance violated his constitutional rights, and that federal prosecutors did not make available to the defense evidence obtained via the surveillance. U.S. District Judge Garr King upheld Mohamud’s conviction, saying that suppressing the evidence collected through NSA surveillance “and a new trial would put defendant in the same position he would have been in if the government notified him of the (surveillance) at the start of the case.”

The surge in murders of polio vaccination workers in Pakistan has made headlines this year, but little attention has been devoted to the ethical issues surrounding the global health impact of current counterterrorism policy and practice. A new study traces the ways that the war on terror is incorporating medicine into warfare – what the researchers call “the militarization of health care” — threatening the health of local populations, increasing global health disparities, and causing profound moral distress among humanitarian and health care workers.

President Barack Obama yesterday announced he had authorized sending up to 300 U.S. troops to Iraq to help the Iraqi military cope with a rapidly advancing attack by Islamist fighters from the fundamentalist group ISIS. “It is in our national security interest not to see an all-out civil war in Iraq,” Obama said. While reiterating that he would not send combat troops to Iraq, the president said the United States would help the Iraqis “take the fight” to the militants, who he said pose a threat to Iraq’s stability and to American interests.

A spokesman for the Iraqi prime minister, Nouri al-Maliki, has said Maliki will not stand down in order to make it politically easier for the United States to launch air strikes against ISIS Sunni militants who have made rapid advances across Iraq, culminating yesterday (Wednesday) with taking control over Iraq’s largest oil refinery, located in Baiji, 130 miles north of Baghdad. The Islamists now control a third of Iraq’s territory. Many U.S. lawmakers, and many analysts of Iraq, consider the failed leadership Maliki — a Shi’a politician who, at Iran’s urging, has pursued a narrow sectarian policies which has alienated Iraq’s Sunnis and Kurds — as the reason for the willingness of the Sunni population in Iraq to welcome ISIS as a protector of Sunni interests, and the indifference shown so far by the Kurds in the face of ISIS gains.
