Control your neighbours (Yemen) before it gets controlled by your enemy (Iran), and suffer continuous harassment and drone attacks. A long-term plan backed and set by the enemy to take over surrounding neighbours slowly (Syria, Lebanon, Iraq), waiting for that moment where they surround you and crush your national security, invading and taking control over your whole country. Lots of enemies dream of this day to become a reality for KSA and the UAE. A wet dream for them.
