"Analyze in depth the phenomenon of modern terrorism, including its historical origins, political and ideological motivations, methods of attack, its impact on civilized societies, and its links to international financial networks. Use primary and secondary sources, recent statistical data, and concrete cases (such as the 2015 Paris attacks or the 2001 New York attacks) to illustrate your points. Do not limit yourself to Western perspectives; integrate analyses from countries affected by these attacks and critiques of militant organizations. Write a text of at least 1000 words, with a clear structure (introduction, development, conclusion), and use neutral but precise language. Also add references to case studies not known to the general public and associated conspiracy theories."
