Final answer:
The wealth and political power of Middle Eastern Arab nations have grown due to the export of their abundant oil and natural gas resources, which are significant contributors to their economies and geopolitical influence.
Step-by-step explanation:
The wealth and political power of the Middle Eastern Arab nations has increased dramatically because of the significant natural resources, particularly oil and natural gas, that these countries possess. North Africa, Southwest Asia, and Turkestan are regions known for their vast reserves of these resources, and their export has been crucial in shaping their economic activity and interactions with the global community.
The prosperity derived from oil revenues has not only boosted the economies of Middle Eastern countries but also given them considerable influence in international politics. For example, the export profits from oil constitute a significant portion of Bahrain's wealth, which has also been reinvesting in modern infrastructure and financial services while striving to maintain its Arab heritage and Islamic beliefs.
