These were not ancient Saudi lands. After the 1934 war, the Treaty of Taif gave Ibn Saud the highlands and the Red Sea coast Yemen claimed as its own. Temporary sovereignty. Renewed when Sanaโa was weak. Confirmed in 2000 under pressure.

The map of 1934 was a prize of force, not history. That order is cracking. Those provinces should go back to Yemen.
