Given the sacrifices that they’ve already made for their cause, most South Yemenis will likely oppose the Saudis’ plot to subordinate them, with the only possible exception being some bribed tribes in the energy-rich East misled by promises of de facto incorporation into the Kingdom.
The Saudis rule the Arabian peninsula so the Yemen's have no choice but to accept what the Saudis say.
They don't rule the Houthi strongholds in the NW Yemen. This fact isn't going to change.
The Saudis and what army as their sucks.
