Let us start with terrorist literature. We focus on jihadi and far-right groups because these are the two ideological families with the longest and best documented history of interest in chemical, biological, radiological, and nuclear (CBRN) weapons use.
JIHADI GROUPS
No group has been under more intense scrutiny for its possible CBRN ambitions than al-Qaida and its affiliates, and for good reason. The 9/11 attacks demonstrated al-Qaida’s willingness to maximize casualties in the West, an intention repeated in word and deed on multiple occasions thereafter. There is ample textual evidence of jihadi interest in CBRN in general, and there is hard evidence of jihadi actual use of chemical weapons5 and of active pursuit of radiological and nuclear (RN) weapons.6
There is no question that at least some jihadi groups are ideologically open to the use of RN weapons. Al-Qaida’s former leader Osama bin Laden spoke repeatedly of nuclear weapons in positive terms as a capability that Muslims have a duty to acquire.7 An al-Qaida-linked cleric, Nasir al-Fahd, issued a fatwa in 2003 sanctioning the use of weapons of mass destruction (aslihat aldimar al-shamil) against Western civilians.8 A leading strategic thinker, Abu Mus‘ab al-Suri, has written extensively on the strategic utility of such weapons and has argued that “hitting the US with WMD… is vital.”9 In 2009 the leader of al-Qaida’s affiliate in Yemen, Nasir al-Wuhayshi, claimed (falsely) that his group possessed nuclear weapons and planned to use them against the United States.10 Technical documentation on RN weapons has been found in al-Qaida’s possession, and on at least one occasion (the José Padilla case) a RN plot was actively contemplated but was scrapped on feasibility grounds.11 Meanwhile, on jihadi Internet forums, anonymous users have regularly fanta-sized about RN weapons, and they have circulated at least one major technical manual (and several smaller ones) on nuclear weapons.12
Islamic State (IS), the most powerful jihadi group in 2016, has not spoken much about CBRN weapons since rising to prominence in mid-2014. Its leader, Abu Bakr al-Baghdadi, and spokesman, Abu Muhammad al-Adnani, have not raised the topic in their speeches after the caliphate was declared in late June 2014. However, one article in the group’s English-language magazine, Dabiq, briefly mentions a specific hypothetical scenario in which IS acquires a nuclear weapon and smuggles it into the United States for detonation.13 Moreover, as a former al-Qaida affiliate that continues to hold Osama bin Laden in great esteem, IS can be assumed to share al-Qaida’s general views of CBRN weapons as legitimate. As discussed later in this chapter, monitoring of a nuclear insider in Belgium in 2015 by IS operatives may be an indicator of nuclear intent. Last but not least, IS and its previous incarnations have a history of chemical weapons use in Iraq since the mid-2000s and possibly in Syria since 2014.14
We should not exaggerate the relative attention paid to RN weapons in jihadi writings. CBRN-related texts make up a small proportion of jihadi texts on tactics, and among these CBRN-related texts, documents focusing on RN weapons are in a minority.15 Bin Laden himself never actually singled out the Bomb as the unconventional weapon of choice; all of his three statements speak of nuclear weapons alongside chemical (and in two instances biological) weapons. Even Nasir al-Fahd’s infamous fatwa is not about nuclear weapons specifically, but rather CBRN in general (in fact, the word nuclear appears only twice in al-Fahd’s text). In short, jihadi groups have explored multiple ways to kill large numbers of people, and RN weapons are only one of them. Still, al-Qaida has said and written more on RN weapons than have most other terrorist groups.
It is therefore interesting that our review of jihadi texts revealed relatively few statements specifically mentioning nuclear facilities. The declarations of Osama bin Laden and Ayman al-Zawahiri lack any suggestions to attack nuclear facilities, as do the Abbottabad documents released so far. Minbar al-Tawhid wa’l-Jihad, the main online archive of jihadi ideological literature, appears to contain no texts explicitly suggesting such attacks. To our knowledge, the only mention by a senior al-Qaida leader of the idea of attacking a nuclear facility occurs in Khalid Sheikh Mohammed’s interview with al-Jazeera in 2002, in which he said that he contemplated using one of the planes in the 9/11 operation to strike a nuclear reactor.16 However, other groups in the wider jihadi movement have mentioned nuclear installations more frequently, not least the Chechen rebels, who made numerous public threats to attack Russian nuclear facilities in the 1990s and early 2000s.17
On jihadi Internet forums, where anonymous jihadis gather for informal discussions, there has also been talk of targeting facilities. However, even here explicit threats are relatively rare. Our search in the Dark Web Forum Portal (DWFP), which covers a variety of forums, some dating back to 2002, uncovered eight posts that revealed a certain interest in attacking nuclear facilities in the West (see the text box for a summary).
Sample jihadi forum messages expressing interest in attacking nuclear facilities
- “Al-Qaida issues statement on the strike against electricity in America” (Montada, August 18, 2003). Post relaying the statement by the “Abu Hafs al-Masri Brigades” (falsely) claiming responsibility for the electricity outage in the U.S. Northeast and Canada. The statement lists fifteen “benefits” of the attack, the eighth of which was “the closing of nine nuclear reactors, which has never happened before and constitutes a powerful economic blow.”
- “Can you present al-Qaida with a plan to hit the Americans and the Brits in their own homes?” (Shamikh, December 1, 2007). Short, somewhat cryptic message that reads: “Can you present al-Qaida with a plan to hit the America and Britain in their own homes?...
