The Saudi's have been making huge arms purchases like this for a very long time. It's all for show and they have never really had to go up against
anyone in a shooting war.
It's all part of the money shuffling that goes on, on a very grand scale indeed. They get $Billions in oil revenue, then invest $Billions in shiny
military hardware, not to mention a few hundred $Millions in kickbacks and arranger fees of course! Not to mention a bit of off the books wheeling
and dealing too.
So, the Saudis are not going to attack anyone with this hardware, especially someone who may shoot back. I mean, it's not like shooting unarmed
Bahrainis, those Iranians have guns too.
Truth is, the Saudi royals are there simply because they will bend over for anyone to remain in power, and with the money they can throw around, they
are also protected by the west. Money talks!
