The Arabian Peninsula comprises seven sovereign states plus portions of two others—not solely Saudi Arabia, though the Kingdom occupies ~80% of the land area.

The peninsula controls ~50% of world proven oil reserves and ~40% of gas, the Strait of Hormuz (UAE/Oman/Iran), Bab el-Mandeb (Yemen/Djibouti/Eritrea), and Islam's two holiest cities (Mecca, Medina in Saudi Arabia). Understanding its multi-state reality is essential for energy, security, and religious geopolitics.
