Answer: 
The political systems created in Southwest Asia after World War I were majorly based on the cultural and regional interests of the natural citizens. 
Step-by-step explanation: 
- By the end of World War I, the European powers completed their conquest of remaining Southwest Asia by bringing the regions of Arabia, Iraq, Syria, Lebanon, Palestine, etc. under their control. 
- The British and French diplomats then met to draw the borders of the Middle East. This resulted in great political unrest in entire Southwest Asia. 
- It also gave birth to different political systems in the region which defended the cultural and geographical interests of the natural inhabitants.
