One theory is Islamophobia. Western power structure create all terrorist group like Al Qaeda, Taliban and now Takfiries and Isis. They make lots of films and advertisement against Islam because they want to increase Islamophobia. Islamophobia (or anti-Muslim sentiment) is a term for prejudice against, hatred towards, or fear of the religion of Islam or Muslims.The term entered into common English usage in 1997 with the publication of a report by the Runnymede Trust condemning negative emotions such as fear, hatred, and dread directed at Islam or Muslims. While the term is now widely used, both the term itself and the underlying concept have been criticized. The causes and characteristics of Islamophobia are still debated.Some scholars have defined it as a type of racism. Some commentators have posited an increase in Islamophobia resulting from the September 11 attacks, while others have associated it with the increased presence of Muslims in secular nations.
ISIL has explained exactly what they want. They want to create a Salafist Sunni Islamic theocracy throughout the Middle East ruled by an absolute dictator (the Caliph) and repress all dissent, especially from Non-Muslims and Shiite Muslims.
Yes. But they were not Twelver Shiites; they were Shiite Muslims of the Ismaili (Sevener) School.
No. ISIL sees Iran as a whole (regardless of its political or factional differences) as an enemy since it (1) is a Shiite-majority state, and (2) is actively assisting Iraq in resisting ISIL incursions.
ISIS is a fanatic organization. It does not want to kill Christians. It wants to establish a state of its own kind of Islam. ISIS people interpret Islam in their own way. They kill even the Muslims who do not agree to their interpretations. They not only dangerous for the Christians, they are equally dangerous to the Muslims.
What is ISIL - ISIS - Islamic State of Iraq and the Levant?ISIL (Islamic State of Iraq and the Levant), known as ad-Dawla al-Eslamiyya al-3iraaq w'ash-Shaam or the acronym Daa3esh in Arabic, is an extremist Sunni Islamist organization. It is important to clarify what Islamism is. While Islam is a religion, Islamism is a political ideology whose goal is to bring the religious tenets of Islam into the daily functioning of a government and its laws. Islamism is a modern movement whose roots began contemporaneously with the rise of Salafism in the late 1800s and early 1900s in Egypt. ISIL practices a particularly violent form of Islamism called Jihadism, which not only wishes a particularly repressive version of Islamic Law to be instituted, but believes that violence in defense of the faith is the preferred way to do this. Jihadism, like Islamism, is a political ideology rooted in Islamic religious concepts, but distorted. The distortion here is that there are many ways to advocate on behalf of the faith and the choice to exclusively use violence is a misinterpretation of the doctrine.ISIL used to have links to al-Qaeda before al-Qaeda condemned them for their barbarity. They are fighting to bring the Sunni majority into power, especially in Sunni majority regions of both Syria and Iraq, and impose a more fundamentalist view on politics. They consider themselves to be fighting the injustices and violence of the current Assad regime and the inequalities of the US-supported Government of Iraq. ISIL is primarily supported and armed by Saudi Arabia, but the US and UK have indirectly given ISIL millions of dollars and equipment since US and UK military vehicles and assets left to the Government of Iraq have fallen into ISIL hands (especially with the fall of Mosul). ISIL controls significant amounts of land in Syria and Iraq and conquered much of its Iraqi territory in June 2014.What is the relationship between Sunni Islam to ISIL?ISIL is an Internationalist Sunni Islamist organization, meaning that ISIL sees itself as "the True Implementation" of Sunni Islam in the world. (Even though its reading of Sunni Islam is just one of a multitude of readings of Sunni Islam.) As a result, they feel it proper to determine laws based on Sunni Islamic Jurisprudence. For example, Sunni Islamic Jurisprudence holds that drinking and smoking is haram (forbidden). As a result, ISIL has banned alcohol and cigarettes. Another aspect of Sunni Islamic Jurisprudence is that a Non-Muslim adversary must be asked to capitulate to Islamic States before Muslims can declare war on them. It is for this reason that ISIL sent a letter to the Assyrians demanding that they capitulate to Islam before attacking Mosul and surrounding Ninewah Province (which had an Assyrian majority in certain areas).Since ISIL considers itself in alignment with Sunni principles, Sunnis are not targeted based on being Sunnis, as opposed to Non-Sunnis who are targeted for death, enslavement, conversion, or dhimmi status. However, ISIL does target any Sunni Muslims for elimination if they disagree with the actions of ISIL or provides an alternate Sunni Islamic interpretation (usually a more lenient one) to the one implemented by ISIL.What is the relationship between Shiite Islam to ISIL?ISIL as a fundamentalist Sunni group, ISIL sees the Shiite Muslims as tafkiris or apostates and treats them as the "enemies of the Muslims". ISIL attacks and detains Shiite Muslims caught in its territory. (Thankfully, there have not been many Shiites in the area that ISIL controls.) This position towards Shiites has resulted in the Republic of Iraq, which is majority Shiite, and Iran, which is also majority Shiite and ruled by Shiite clerics, aligning together to target ISIL for attacks and violence. Press TV, Iran's state news media, has responded to ISIL allegations that the Shiites are takfiri by naming ISIL as takfiri. Additionally, the Assad Regime is led by the Alawite minority which were granted "honorary Shiite status" by the Iranian Shiite Clerics. As Assad is also opposed to ISIL, it amplifies the Shiite hatred of ISIL and ISIL's hatred of Shiites.
As far as I am aware, there is no Shiite Islamic community in Israel. The Muslims in Israel are primarily Sunnis.
No. For Shiites and Christians, the answer is unequivocally no. ISIL only accepts Sunni Muslims who agree with their particular Islamist and Jihadist views. As for Kurds, while it is possible to imagine a few Kurds being swayed by ISIL arguments, the majority of Kurds would see joining ISIL to be a betrayal of everything it means to be a Kurd because of ISIL's current wars against both Iraqi Kurdistan and Syrian Kurdistan.As concerns the nonsense claim in the Community Answer about Shiites not being terrorists (just like Sunnis), please see this Related Question: Can Shiite Muslims be terrorists?
There are more Sunni Muslims than Shiite Muslims. Shiite Muslims represent about 15% of the global Islamic community whereas Sunni Muslims represent 85%. The numbers of the other sects are negligible.
No. They are almost all Sunni Muslims.
Sunnis
Shi'ite Muslims worship in Mosques as do Sunni Muslims.
Yes. Shiite Muslims are allowed to perform the hajj, but they cannot perform any rituals unique to Shiite Islam while in Saudi Arabia or they risk arrest or deportation.
