IMO, its about oil. If the Deep State can foment ill will between Trump and Saudi Arabia, the hope is they would curtail oil production (or an embargo), cause an oil price spike, and precipitate a worldwide recession.
Presto, Trump’s main accomplishment - the booming economy - would go away.
It’s for the same reason they want a war with Russia.
That makes sense.
Finding radical Islam and 9/11 = ignored for years.
Now they want to stir up an embargo.
Must be to tank our economy. Hurt Trump.
