The agreement is for the purchase of a number of F-15 fighter jets, a sale which the Pentagon says will ensure that Qatar has “state-of-the-art” defensive capabilities. Qatar is the richest nation on the planet in per-capital GDP, but a very small nation to be spending $12 billion on warplanes. Over the past couple of decades, oil-rich Gulf Arab states have used some of their massive oil revenue to buy US warplanes as sort of prestige pieces to trot out during parades and the like. That tensions are rising between Qatar and the other nations, who have their own large fleets of US warplanes, but this purchase in a totally different context.
All of this comes just a day after the Ambassador from the United Arab Emirates suggested the US should move their base out of Qatar to “pressure” them. That, it seems, is not under serious consideration from the Pentagon.
