Spiegel has stirred up a scandal by reporting about an apparently pending export of heavy wheeled APCs (MRAV, GTK, Boxer - choose a name) to Saudi Arabia, and it should.
I remember an article about a Saudi motorised (= wheeled armoured vehicles) regiment written by a Saudi officer and published in if I remember correctly either Armor Magazine or Infantry Journal, official U.S.Army publications. I didn't archive it, didn't find it again in the former and honestly don't know where in the archive of the latter is hidden. It may be behind the stupid AKO account firewall which Armor Magazine and Infantry Journal editors opposed so very much when it was introduced during the early GWOT craze.
Anyway; said article was perfectly clear that such wheeled armour Saudi troops were first and foremost meant to defend the regime domestically, being able to deploy on road to any domestic trouble spot in short notice (unlike tracked forces would typically do, or so was the opinion of the 90's). Going to battle against another military came second.
The scandal is a scandal because of this potential, without the people talking about the scandal even knowing how very much focused said Saudi army troops were and certainly still are on the domestic suppression role.
We shouldn't do business with the Saudis, who come most close of all to meeting the generally wrong Muslim/Arab stereotype of being dark age people. Their state is -by European standards- a single huge abomination, and we should apply ours standards when doing business in the world.
Doing business with Saudis is generally a poor idea for another reason; their inherent corruption tends to taint the ones who do business with them, there's too often some bribing by or of Germans involved when we do such business.
edit: Found the article. It's in Armor magazine March/April '96!
