A Twitter post Thursday by supporters of the Islamic State of Iraq and Syria (ISIS), now calling itself the Islamic State (IS), has 
promised a Holocaust against the Jews.
“The Real Zionist Holocaust is Predicted in the Hadiths! The Hour [resurrection] will not take place until the Muslims fight the Jews and the Muslims kill them, and the tree will say: “Oh, Muslim, servant of God, there is a Jew behind me, kill him! THE PROMISED Holocaust,” the terrorist group’s Islamic State Media a graphic posted on its @ISIS_Conquests’s Twitter account said.
This hadith has proven popular with Islamic extremists of all stripes, ranging from IS to Hamas – and even on television in the Middle East.
Daniel Pipes, an expert on jihadism, said the hadith likely was a recruitment tool.
“Yes, calling for a holocaust against Jews refers to a violently anti-Semitic strain among jihadis and will surely appeal to some of them,” Pipes said in an email to the Investigative Project on Terrorism.
Anti-Semitic propaganda has played an important role in the terrorist group’s recruitment effort. Its leader, Abu Bakr al-Baghdadi, placed Jews on the side of evil in a speech posted Tuesday on the Internet in which he called on Muslims to join him.
“O ummah of Islam, the world today has been divided into two camps and two trenches … The camp of Islam and faith, and the camp of kufr (disbelief) and hypocrisy … all being led by America and Russia, and being mobilized by the Jews,” al-Baghdadi said.
In another such video released on Twitter, IS told jihadists to “Break the crosses and destroy the lineage of the grandsons of monkeys.”
Some jihadist supporters are calling on the group to open a new front against Israel.
“@ISIS_Conquests Hey #ISIS please do us all a favour & open up a front against Israel. Surely they are the greatest enemy of humanity?” Akhmet Qassam, a supporter from Scotland, asked the group on Sunday. “@ISIS_Conquests If you open up a front against #Israel I’m sure your numbers will increase hugely. Also give you some legitimacy.”
At the same time, IS may be growing cautious about drawing unwanted attention from Western intelligence and law-enforcement agencies even as it seeks new recruits.
“All Brothers and Sisters…Don’t meet with IS members while you’re living in the West…Move out of the West & than (sic) you get in touch with IS,” @Dawla_Newsmedia wrote a day after U.S. law enforcement caught Shannon Maureen Conley, a 19-year-old woman from Denver, trying to leave the U.S. to join the IS.

The Investigative Project on Terrorism (IPT) is a non-profit research group founded by Steven Emerson in 1995. It is recognized as the world’s most comprehensive data center on radical Islamic terrorist groups. For more than a decade, the IPT has investigated the operations, funding, activities and front groups of Islamic terrorist and extremist groups in the United States and around the world. It has become a principal source of critical evidence to a wide variety of government offices and law enforcement agencies, as well as the U.S. Congress and numerous public policy forums. Research carried out by the IPT team has formed the basis for thousands of articles and television specials on the subject of radical Islamic involvement in terrorism, and has even led to successful government action against terrorists and financiers based in the United States.
