Terrorists strike Iran? Isn’t Iran a source of terrorists?

Why is the Middle East so turbulent?

The Middle East is a very complex place for Westerners who have not studied or lived in it to understand. This simple backgrounder offers a brief explanation.

A long held partial explanation for the region’s turbulence has been rooted in the post-WWI partitioning of land along geopolitical lines ignoring ancient cultural and tribal traditions. Not only did that sow the seeds of instability but also fostered hostility toward the Western nations that imposed it. Religious divisions have defined the more recent regional antagonisms.

Aren’t all Muslims followers of Islam?

Islam is the 2nd largest religion in the world (Christianity is the largest) with 1.8 billion followers. While Christianity has a number of denominations, e.g., Catholic, Protestant, Baptist, Methodist, etc., Islam has basically two: Sunni and Shi’a. A non-Muslim might think the differences are subtle (like Catholics and Protestants who simply agree to disagree). The divisions are firm, however, which has internally bound the respective communities but also created interdenominational tensions, sometimes to extremes. For more detailed background, see:

Why was Iran – a Muslim-majority country – attacked by Muslim extremists?
While Shi’a followers make up only 10-15% of worldwide Muslims, they form a majority in Iran (95% Shi’a) and Iraq (65%). All other Muslim countries in the world (except Lebanon) have substantial Sunni majorities. In the region, this includes Saudi Arabia (88% Sunni), Egypt (99%), Syria (74%) and Turkey (73%). This makes Iran a target for Sunni extremism. While extremists and terrorists are the tiniest minorities within any group, Sunni extremists may try to destabilize Shi’a-majority Muslim countries like Iran and Iraq.

Are the names we hear in the news related to specific Islamic denominations?

The names of terrorist groups in the news sometimes can be linked to denominations of Islam but the incentives for terrorism are almost always multifaceted, reaching beyond simple theology to economics, politics and history. Therefore the general term “Islamic terrorism” is no more accurate or specific than labeling bombing of Planned Parenthood clinics as “Christian terrorism.”
