So yeah, to hell with the Saudis and the camels they rode in on...

Thx for all these references. Upon looking at them, it is obvious that the US should be on guard toward any efforts by the government of Saudi Arabia to radicalize elements within our country. As you suggest, that should include, among other things, perhaps a ban on mineral exploitation and property here by SA.
That does not mean we are absent from doing any and all business with that country. The US still needs its resources to continue our standard of living, we just need to utilize these resources under our own control.
The elements which are the worst in radical Islam come from the Iranians and those countries and elements Iran backs. I would never accept Iranian crude into this country, and would not accept Iranian citizens unless they are highly screened.
The Saudis need us as much or more than we need them. We can never permit their resource bounty to fall into the hands of the Russia/China alliance, nor be blackmailed into submission by the radicals of Iran, which is one reason we have our relationship with them since the 1940s.
Trump has been braying about the US containing the world's largest hydrocarbon resource, which is misleading if not wildly incorrect. We have a lot for sure, but most is comparatively expensive to attain and will be a prolonged time until it is fully accessed. Accessing that oil and gas should be a national priority as it creates wealth for us rather than giving our wealth to other countries; however, domestic production will never be enough to satisfy our energy needs.
For generations to come, the world's most plentiful and cheaply attained reserves of oil exist in the Middle East, which causes all countries who wish to prosper to deal with those countries, not to destroy relationships with them. There are exceptions, such as the Mullahs of Iran, who cannot be dealt with nor trusted.
As long as the kingdom of Saudi Arabia is run by the Saud family, it will be one we can deal with to continue/improve our living standards. If that family becomes fractionated, then all hell will break loose on the world stage as energy access will be a whole new game.
Ferreting out radicals within Islam should be the priority here. It is not in the interests of the Saud family to promote these elements. The real problem for us Westerners is that we have limited ability to discern who among the Muslim world is radical or not, so we throw them all in a catch-all group to our detriment. So the only way we Westerners can react is to simply say we ban all of them, which does not serve our needs well. What is really needed is for Muslims themselves to identify the radical Muslims as they best know who they are. And the Muslim world has more effective methods of dealing with them than we do. There are no Guantanamo Bay resorts in the ME, just torture chambers.
There are ways we can take to gradually lessen our reliance upon Middle Eastern crude, such as improved relationships with our neighbor Canada, resurgence of nuclear power, and focused development of gas-to-liquids improvements as our abundance of natural gas far exceeds that of crude oil. This will take time and a commitment over a generation to obtain.
Finally, I have no desire to further the expansion of Islamic peoples or institutions within our country. We just need to work with them intelligently.
