The excuse being offered is that Iran is no longer a threat. . The reason (as distinct from the cover story) has more likely to do with Trump's concern about the low oil price and how inadequate returns are sending America's shale oil firms broke.https://www.marketwatch.com/story/us-to ... -121035610
The U.S. is removing Patriot antimissile systems from Saudi Arabia and is considering reductions to other military capabilities, marking the end, for now, of a large-scale military buildup to counter Iran, according to U.S. officials.
The U.S. is removing four Patriot missile batteries from Saudi Arabia along with dozens of military personnel sent following a series of attacks on the Saudi oil facilities last year, according to several U.S. officials. The attacks were part of hostilities that took place over several months.
Two U.S. jet fighter squadrons also have left the region, and U.S. officials also will consider a reduction soon in the U.S. Navy presence in the Persian Gulf, the officials said. The redeployment of the Patriot systems, which now is under way, hasn’t been previously disclosed.
The removals could well be a nefarious "waving a red rag at the bull".
With the patriot batteries removed the Saudi oil terminal facilites on The Gulf are well neigh defenceless. Imagine if Iran were to make a strike now; possibly through their surrogate in Yemen in order to destroy Saudi Arabia's oil exporting capacity.
So much crude oil will be subtracted from the global market that the world price would have to rise. US shale oil might even become cost-effective to produce again.
