Setting aside sarcasm and entertainment, the Islamic world does indeed have a greater propensity for internal infighting and is more susceptible to external manipulation.
I once commissioned an AI to conduct a data analysis. To avoid the significant margins of error found in older records, I focused on data spanning from the end of World War II to the present. The findings revealed that the number of Muslim deaths resulting from direct, internal sectarian violence far exceeds the number of deaths caused by conflicts between the Islamic world and the non-Islamic world.
For instance, regarding the war in Iraq, casualties inflicted by the U.S. on Iraqis were tallied separately from those resulting from internal factional conflicts; the same methodology was applied to the war in Afghanistan. Even though many of these factional clashes were orchestrated or instigated by external forces, they were still classified as direct, internal violence within the Islamic world.
This is a matter that warrants deep reflection.
