ISIS new tacktics strategy...Lone wolf attacks.

Even though ISIS is defeated in Syria, but the threat is still looming, and this threat is not confined in Europe or USA, it can be considered as a worldwide threat since it is a decentralized operation. We saw some operations in several countries, and the recent bloody one is in Sri Lanka, the operations which are conducted by Lone wolf strategy, that is manifesting a real threat of new face of terrorism . The adoption of Lone wolf by ISIS is more clearly manifested in a recorded audio message , when the spokesman of ISIS Abu Muhammad al-Adnani asked the sympathizers and supporters with the organization to carry out killing operations against nationals of coalition countries (Recent coalition against the Islamic state) anywhere and by any means available. Urging more attacks on Western interests everywhere, saying that:" targeting so-called civilians is the most favorite and the most beneficial, "there is no immaculacy on bloodshed and no innocent people, and if you do not find a weapon, trample them with your own cars." The phenomena of Lone wolf terrorist is a complicated one; they are individuals with no organizational affiliation and no sources to receive instructions and assignments, they carry out terrorist acts depending on their potential, influenced by extremist movements or based on ideological, religious or political convictions.
Three needed criteria should be included in Lone wolf terrorist act, the act should be done individually, even if the Lone wolf does not belong to a terrorist organization and the process should be planned without the involvement of any external elements or organizational leaders. Lone wolves are carrying out individual operations against a community.
Unlike traditional terrorists, Lone wolves often combine personal vendetta with religious or collective political grievances. Together, they constitute a powerful impetus to challenge the desired target.
Some of the operation’s forms that can be done by the Lone wolves are: planting self-made bombs in different locations and detonating them remotely, or conduct an individual attack with a weapon that can be manufactured at home or legally purchased in the countries that permit its sale (like USA), or driving a car or a truck and trampling pedestrians, or use bladed weapons. All of these are planned, self-financed and strictly confidential acts of Lone wolf terrorists.
The term "Lone wolf" got famous because of al-Qaeda and ISIS attacks in the European countries and the United States of America, even though there are several Lone wolf attacks which date back for decades and the tactics are not confined to Islamic terrorism as evident in the recent New Zealand attacks and attack in Norway in 2011 .
Current Islamic Lone wolf terrorists do not appear to be religious or hard-line. On the contrary, they drink alcohol, take drugs, and have sexual intercourse. One of the most famous Lone wolves in the world, Ted Kaczynski, a Harvard graduate and a former mathematician, planned and carried out 16 separate explosions over the period of 17 years, from 1978 to 1995, killing 3 and injuring 23 people, and that was for the Federal Bureau of Investigation the longest and most expensive investigation in their history .
Timothy McVeigh, an extreme right-winger, and former US Army soldier was the mastermind of the Oklahoma City bombing on April 19, 1995. He killed 168 people and injured more than 500, and this is still considered to be the worst domestic terrorist incident in the history of United States . As well as the extreme right-winger Anders Breivik, who killed dozens of people in Norway in 2011, in protest against his country's policy and acceptance of immigration of foreigners .
