Problem: (CNN)For a group of radical anti-Western militants, ISIS is pretty good at luring Westerners to its ranks.

The latest is an American teen from suburban Chicago who was allegedly on his way to join ISIS. Mohammed Hamzah Khan was stopped just before he was supposed to board a plane to Turkey, authorities said.

But he's far from alone.

Last month, U.S. authorities detailed their case against a New York food store owner accused of funding ISIS and plotting to gun down American troops who had served in Iraq.

And a French man told his mother that he and his half-brother were going on vacation -- only to tell her later that they were fighting in Syria.

"Some of the foreign fighters may not return as terrorists to their respective countries, but all of them will have been exposed to an environment of sustained radicalization and violence with unknowable but worrying consequences," Richard Barrett of The Soufan Group wrote in a report called "Foreign fighters in Syria" this summer.

So what is it about ISIS and its uncanny ability to recruit Westerners? Here are five methods the group employs:

It preys on a recruit's sense of identity

The recruits are often young -- sometimes disillusioned teenagers trying to find purpose and make their mark.

For many, it boils down to a lack of a sense of identity or belonging, Barrett said.

"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," he wrote.

Problem: Sofia ( or or ; , "", ) is the capital and largest city of Bulgaria. 1.26 million people live in the city and 1.68 million people live in its metropolitan area. The city is at the foot of Vitosha Mountain in the western part of the country. Being in the centre of the Balkan peninsula, it is midway between the Black Sea and the Adriatic Sea, and closest to the Aegean Sea.

Sofia has been an area of human habitation since at least 7000 BC. Being Bulgaria's primate city, Sofia is a hometown of many of the major local universities, cultural institutions and commercial companies. Sofia is one of the top 10 best places for start-up business in the world, especially in information technologies. Sofia is Europe's most affordable capital to visit .

For the longest time the city possessed a Thracian name, derived from the tribe "Serdi", who were either of Thracian, Celtic, or mixed Thracian-Celtic origin. The Serdi and the name of emperor Marcus Ulpius Traianus (53 117 AD) prompted the Romans to give the city the combinative name of "Ulpia Serdica"; Ulpia is derived from an Umbrian cognate of the Latin word "lupus", meaning "wolf." It seems that the first written mention of "Serdica" was made during his reign and the last mention was in the 19th century in a Bulgarian text (, "Sardaki"). During the Romans "civitas Serdenisium" was mentioned the "brightest city of the Serdi" in official inscriptions. The city was major throughout the past ever since Antiquity, when Roman emperor Constantine the Great referred to it as "my Rome", and it nearly became his capital.

Problem: An airport is an aerodrome with facilities for flights to take off and land. Airports often have facilities to store and maintain aircraft, and a control tower. An airport consists of a landing area, which comprises an aerially accessible open space including at least one operationally active surface such as a runway for a plane to take off or a helipad, and often includes adjacent utility buildings such as control towers, hangars and terminals. Larger airports may have fixed base operator services, airport aprons, air traffic control centres, passenger facilities such as restaurants and lounges, and emergency services.

The majority of the world's airports are non-towered, with no air traffic control presence. Busy airports have air traffic control (ATC) system. All airports use a traffic pattern to assure smooth traffic flow between departing and arriving aircraft. There are a number of aids available to pilots, though not all airports are equipped with them. Many airports have lighting that help guide planes using the runways and taxiways at night or in rain, snow, or fog. In the U.S. and Canada, the vast majority of airports, large and small, will either have some form of automated airport weather station, a human observer or a combination of the two. Air safety is an important concern in the operation of an airport, and airports often have their own safety services.
