Let me give a little more context. Saudi Arabia had a relationship with the US early on and it was US contractors who developed the oil there initially. This is a very old relationship, basically it is the bases of Saudi Arabia, the realized early how powerful to US was and attached themselves.

The Saudi were very anti-Communist and opposed Arab nationalist (a 'socialist' type regime) in Egypt. In a period known as 'Arab Cold War'.

There was a fear that most of the middle east would unify under Arab nationalism. The Saudi were opposed that.

A second important part is the sale of oil, people will often argue that this is less important now because domestic production. However it was always more about European and later Asian allies of the US and ensuring oil for them.

The relations were at is worse during the oil crisis. However once the Iranian revolution happened, and Iran was no longer an US ally there was major fear of Soviet invasion or Iranian revolution spreadng. Jimmy Carter declared the 'Carter doctrine':

> Let our position be absolutely clear: An attempt by any outside force to gain control of the Persian Gulf region will be regarded as an assault on the vital interests of the United States of America, and such an assault will be repelled by any means necessary, including military force.

Since their major client Iran was gone the US basically 'had to' depend on Saudi Arabia.

This was then majorly expanded upon by Reagan. While up to this point, relation were diplomatic (and CIA blabla) under Reagan there was a militarization. Bases were starting to build in the region and the US wanted to sell more weapons to the Saudi, Qatar, Bahrain as well.

The US started to build bases in Saudi itself during the first Golf War (that was the major reason for 9/11 btw).

Since 9/11 despise what the general population wants (and correctly believes), politically the US sees Saudi as a major ally in the 'fight for terrorism' when it is convenient but the consistent opposition to Iran is arguably the more important part.

Saudi Arabia has also totally sold out the Palestinians and has been practically allied with Israel.

So here are why the US politicians continue this 'partnership':

- Major oil state that insures sale to European and Asian allies

- Oppose Iran

- Oppose the Islamic Brotherhood (Saudi paid for the overthrow of the Egyptian 'democracy')

- Saudi regime drove AQAP (Al Quida Arab Peninsula) out of Saudi and pretends to fight them in Yemen

- Saudi (and golf state) buy a gigantic amount weapons to the point where Trump basically treated the Crown Prince like cash cow and made him do TV ads with him

- Saudi spend a lot of lobbying and fund many of the 'think tanks'

- Saudi and Israel get along

However, this episode here that so many people car about is literally never what the US cared about. An allied regime killing journalist is about as interesting as empty glass of water. To me this is a total non-story.

This is only a media outrage story. The US routinely helps in repression of journalists and what the US/Saudi are doing in Yemen is about a million times were the this Khashoggi thing. Not to mention that they are also oppressing and killing journalist there too, but I guess there are not good videos of it so it can be safely ignored.

In my opinion the whole strategic approach the US has towards the Saudi and the Middle East in general is fundamentally flawed and pilled on top of a whole bunch of wrong assumption.

Unfortunately realignment in foreign policy is very difficult. With Israel and Saudi (and co) money continually buying of congress/Washington while Iran and others don't have such powerful lobbying organizations within the US.
