First, don't forget that Britain and France had immense roles in defining what became the countries of I ran, Iraq, Saudi Arabia, Israel, Egypt, Jordan, et al. after World Wars I and II.

Secondly, a recent decision was made to allow Saudi Arabia to make US "smart bombs" and the technology to do so has already been transferred.

Thirdly, with the decision by Iraq to require the removal of ALL US forces there and the statement by you-know-who to slam the Iraqis with heavy sanctions if such removal happens, Iraq will move to Iran for help. This will pit Iraq/Iran against the Saudis, and Kuwait and the Gulf States will get the short end of it.

Fourthly, the US Navy very recently decided to cut way, way back on shipbuilding in 2020 and has given up its plans for a 595 ship fleet (I think that was the number).

You can think of more, I'm sure.
