Despite the world counter-ISIS attacks and plans, but the terrorist group is still successful in luring many westerners. the world media have also been launching a major fight warning against the different methods the group uses to brain wash those young people to join them.The latest may be 11 foreign medical students whose families fear they might have gone to Syria to work in ISIS-controlled hospitals. Last month, three teenage British girls suspected of wanting to join ISIS may have gone to Syria, authorities said. Their fates remain unknown. An estimated 3,400 Westerners have gone to join ISIS in their bloody quest to establish an Islamist state in Iraq and Syria, said Nicholas Rasmussen, director of the National Counterterrorism Center. So why is ISIS so skilled at luring Westerners? Let us find out the answer of such an important question with the CNN. 1-ISIS recruits are often young -- sometimes disillusioned teenagers trying to find purpose and make their mark. "The general picture provided by foreign fighters of their lives in Syria suggests camaraderie, good morale and purposeful activity, all mixed in with a sense of understated heroism, designed to attract their friends as well as to boost their own self-esteem," counterterrorism expert Richard Barrett wrote last year in a report called "Foreign fighters in Syria." Fawaz Gerges, professor of Middle East studies at The London School of Economics, put it more bluntly: "ISIS provides these deluded young men and women with an adventurous trip." Many recruits come from educated, well-to-do backgrounds, like 25-year-old Abu Anwar of Britain. He said he had no problem leaving a comfortable lifestyle to join ISIS. "I'm from the south of England. I grew up in a middle-class family," he told CNN. "Life was easy back home. I had a life. I had a car. But the thing is, you cannot practice Islam back home. We see all around us evil. We see pedophiles. We see homosexuality. We see crime. We see rape." 2-Some are lured by the possibility of dying as a martyr so they can enjoy a sumptuous afterlife.Others may succumb to more tangible promises. ISIS loyalists are told they will receive gifts from Allah, wrote Aqsa Mahmood, a young British woman who left Scotland to join ISIS and now is an ISIS recruiter. Such gifts include "a house with free electricity and water provided to you due to the Khilafah (the caliphate or state) and no rent included," Mahmood wrote. 3-ISIS' slick propaganda videos resemble trailers for Hollywood action movies. ISIS now has the most sophisticated propaganda machine of any terrorist organization, said Matthew Olsen, director of the National Counterterrorism Center. "It turns out timely, high-quality media, and it uses social media to secure a widespread following," he said. Even the U.S. State Department admits ISIS' propaganda prowess "is something we have not seen before." "It's something we need to do a lot more work on," State Department spokeswoman Jen Psaki said last month. "We are seeing 90,000, I think, tweets a day that we're combating." 4-"This is a political cult using religion and a perversion of Islam as the shield," said Steve Hassan, founder of Freedom of Mind, a group dedicated to exposing destructive cults and cult behavior. "But in fact, it's a systematic effort to create an army of basically tranced-out followers." That type of brainwashing is what turned Canadian Damian Clairmont into an ISIS militant, said his mother, Christianne Boudreau. "It's so easy for them to get to our children, to access our children," she said. 5-About 130 Canadian citizens have traveled to the Middle East to join ISIS, Canada's intelligence agency estimated last yearAbout 1,200 French fighters have joined ISIS as well. Roughly 600 British nationals are believed to have gone to Iraq and Syria, according to research groups, along with another 600 from Germany. In the United States, National Intelligence Director James Clapper has said 180 Americans have tried to go to fight in Syria. But it's unclear how many of those were attempting to join ISIS. Once foreigners go to Iraq or Syria to join ISIS, their odds of going back to their families can be slim. Video clips of foreign jihadists burning their passports show that many have no interest in returning home. 6-"We are way behind. They are far superior and advanced than we are when it comes to new media technologies," Maajid Nawaz, a former jihadi and author of "Radical: My Journey out of Islamist Extremism," told CNN last year. British Prime Minister David Cameron has said the case of the three British girls highlights the need to fight ISIS on multiple fronts."It needs every school, every university, every college, every community to recognize they have a role to play, we all have a role to play in stopping people from having their minds poisoned by this appalling death cult," he said. The U.S. government is trying to step up its efforts to counter ISIS propaganda by beefing up a small State Department agency to make it the heart of the fight against the militants' messaging. "We're seeing their approaches continue to evolve," Psaki told CNN. "We need to continue to make sure ours are evolving and we're combating it in the most strategic way and using every interagency resource." But she acknowledged that the United States still has a lot to do. "We're really going to pick it up now," Psaki said. "We have new people in charge of the office. And we will see what happens over the coming months."But several anti-ISIS efforts are already in place. Some European countries have laws that penalize membership in groups such as ISIS, said Barrett, the counterterrorism expert. And U.S. State Department official Richard Stengel said an anti-ISIS messaging campaign has helped prevent youths from joining. "They're reading the messages, they're hearing the messages -- not just from us but from the hundreds of Islamic clerics who have said that this is a perversion of Islam, from the hundreds of Islamic scholars who have said the same thing," Stengel said in October. But Barrett said some officials might not be doing as much as they think. "Policymakers often underestimate the impact of what is happening in these closed circles even as they overestimate the impact of their own."
